Sprint boosters work. Depending on the setting, it reduces or eliminates the electronic delay when you press your accelerator pedal. As cars are now drive my wire, the manufacturers purposely put a .4-.5 second delay on the accelerator as a "safety" devise so the car gas pedal does not feel jumpy. (It mimics the old gas pedals that were drive by wire.)

With that said, the effects of a sprint booster can also be achieved through a tune and reprogram of the ECU.

I recalled my M3 had that pwr button which did the same. It made the car quite jumpy and I didn't like it at all.

I experienced that slight delay on the Z with the air on a couple of times, but I think it is fine with normal driving.

I just installed one about 2 hours ago. Tomorrow I am going to check it out if it doesn't rain. Throttle response improved after my Uprev tune so this should be a great finisher. I'll let you know when I am done with the road test.

Installing SprintBooster after a tune is pretty much pointless since your tune should already address the throttle lag. All you are doing is essentially shortening the gas pedal throw so that you hit WOT at around 70% pedal travel.

30 day money back guarantee. If it is not an improvement, back it goes. I'll report back. I improved my clutch pedal by upgrading. This is just an experiment. I'm hoping it succeeds. My throttle still leaves a little to be desired. My car roars no doubt. But if it's crap it goes back. If not it stays. Ill shoot you straight on the results.

You'll probably still notice something by installing Sprintbooster because all it does is increase your throttle voltage a tad making the car think you pushed the gas pedal further than you have. My point was since you can make throttle response adjustments properly with a tune, why not just have your tuner make the adjustment and leave sprintbooster out of the equation?

I clearly have done my research on this before I invested the money to take the chance. What you gain from the sprint booster is it quicker wide open throttle. All this thing really is a capacitor that holds a charge that increases the voltage as the accelerator pedal pressed down. It has nothing to do with the length of travel it has everything to do with the throttle plate opening up faster. These are in different cars called different things in all kinds of sport models from BMW's to Mini Coopers to everything else. This isn't new science. Just something to add an accent on something that already works

If it makes for a better Driving Experience I will tell you and I will recommend it. If it's snake oil and give me a key I'll tell you that too. I'm a serious man it's been serious money for serious fun. If the dollars don't make the sense it won't happen. I put 73 millimeter throttle bodies on my car thinking more or would be better but the tuner couldn't even balance it out with the air fuel ratio. So that was an $800 idea it was taken off the car and sent back. Good concept bad effect

our cars shouldve come with adjustable throttle responses to begin with. so even with or without a tune if it improves ur driving enjoyment, i say go for it.

not like sprint booster costs much anyway, and easy to install.
wat i like best about it is u can set it up one way and forget about it.. and no need for outside intervention. i like dat. i hate taking my cars to the shops just to get a tune.

I've had mine for a over a year now and it stands up to all the hype. Works just as it's advertised and I wouldn't even wanna drive my Z without it. Night and day from stock.

:iagree: considering how sloppy the csc is, the sprint booster is enough for the throttle side.

Obviously you're not understanding that you can do this with your tune and have no need for the sprintbooster. You can adjust throttle response in your tune to open up the throttle plate as quickly as you want.

The downside of sprintbooster is that it will decrease the pedal travel needed to hit WOT. I do not understand why you would want to do this as it decreases the accuracy of your throttle input. Especially when you already have a tune that can be adjusted to open throttle plates as quickly as you want.

It's installed now to test. If it doesn't offer any improvement I'll send it back and have enough for 2 hours at the tuner. I'm really not going to overthink it. Imo the stock clutch was the strangest I had ever used. I upgraded to the RJM and now the Z feels way smoother when shifting from launch on. So in conclusion if a mod improves my personal driving experience I will check it out. Looking forward to an honest assessment to offer you. This could be whack. This could be awesome. Let you know....

Ok, this will be the last :horse: post from me.

I would fully expect you to notice a difference when you install sprintbooster regardless of whether you have a tune. My only point was that if you already have a tune, your tuner can adjust your tune further to do exactly what sprintbooster is doing (actually it will do it better because it will keep WOT at full pedal travel giving you maximum throttle input accuracy). So you don't really need the sprintbooster. Installing it with your tune is going to have an effect ... similar to if you had asked your tuner to do some additional adjustments to the throttle maps in your tune without ever installing sb.

It's your car and your money, so you do what makes you happy :tup: :driving:
If the sb gives you what you want and you don't have to go back to your tuner, then cool :)

I have not had a chance to get the Z out yet because it never stops raining. Spoke with my tuner this morning and he confirmed that Uprev has a preset parameter that changes the throttle response. He said unless prompted he does not adjust anything beyond that. He said if he spent the time he could get more but only by request.

A local guy here had his Z tuned with Uprev but they did not adjust the throttle map, he now has a SB unit to go along with his tune. Last time I spoke with him he was happy with the result of the combination. Also another local guy with a Stillen SC, also tuned on Uprev and did not adjust the throttle, he too runs an SB unit with the SC.

If you have the cable and license you can just upload your own throttle tables? Or you can just ask your tuner to input this throttle table, it seems like these members were pretty happy with it.

:facepalm:

As I sit here watching the premiere of Street Outlaws I wanted to give you my report on the Sprint Booster. Brace yourselves for the truth........

Unbelievably Incredible! Let ALL the non believers know. For the $1000's I've invested this single unit has the biggest instantaneous improvement to the Z's performance. I'm officially impressed and want to recommend this to the Z lover's everywhere. Any smack-talking to the contrary to this it's just that smack talk. Put out the money put it where your mouth is May down to three hundred bucks hook this thing up and if I'm full of it you can send it back and get your money back but if not you can thank me and the guy who invented this thing for letting you know. There are a bunch of other types of these things on the internet as well this isn't the only one but it is easy to hook up and use and the results are amazing

Looking for you JarBlue

welcome to like 5yrs ago..

Nice to have arrived. Had the Z only a little over a year. Incredible journey from then til now. Quite a car. This was the cherry on the Sundae for sure. Untaps all available horepower. It has not added any, just lets me get to the ones I've got, quicker. So thanks again for the unique welcome. I accept.

Calling me out now? :rolleyes:

If you'll recall, I fully expected you to be impressed with the shortened pedal throw and loss of throttle input accuracy that sprintbooster provides :ugh2:

Just wanted you to know you might expand mind to considering this. Imo... it's an easy adjustment for the pedal. No problem at takeoff no problem shifting nothing. But when you want to put your foot in it it's there for you instantly. I don't feel at a loss because I'm missing the last little bit of travel in that pedal one bit. It's funny when you switch it back to stock mode. I used to think it was so fast then. The response now is immediate. For me personally it's all about the Driving Experience. If I can advance that through horsepower, other mods and now this, I'm all for it. I would say most of everything I've done to my car has been gleaned off information on this forum. Trying to take care and improve on all the areas of the car that need it. All I'm trying to do is contribute to this group of members to let them know if this is a money-back chance at improving the performance of their car. That's all. I'm not selling this product. I may buy another for another vehicle at some point. But I am a believer and I want you all to enjoy your car as much as I enjoy mine. I'm out

Have you guys heard of Sprint booster
 

Dude, everything you experienced with this part is available through your tuner. You didn't have to buy another part, all you needed to do was tell your tuner to use the throttle map posted here. Of course you notice a difference. That was never in question. You just didn't have to pay more for it.

And if your tuner didn't take the time to adjust the throttle, what else did he not do? Did he adjust the fan tables, or is that a "special request only" item like the throttle?

The coolest features about sprintbooster are the relatively inexpensive cost (compared to full tune), the ease of installation, and the ability to switch between three different modes on demand. It is fantastic for people who don't want to tune for various understandable reasons. There's really only one downside, which I've pointed out way too many times already. It's not a bad mod at all - I understand exactly what it does.

My only point ever in this particular conversation with you was that you paid a lot of money (I assume) for a tune and improved throttle response to your satisfaction should have been part of that. I had my car tuned when it was essentially stock, and the throttle response was phenomenal - exactly like what you are experiencing with Sprintbooster.

Will I get back in touch with my tuner. I guess you need to go in there with a set list of what you're looking for for improvements on your tune. This guy spend an extra 2 hours trying to calibrate my 700 CFM throttle bodies on my car and he couldn't do it so I ended up having to send them back because the car could never reach Idol. He said he could do it but it cost me. He said he'd never do another throttle body conversion like that again. I'm probably going to switch to ECUtek anyway.

But I am going to contact him and another tuner shortly to see if I can get the same response from the pedal and I will send that thing back. I thought I had maxed out with what the Uprev could do. But if you guys are telling me I can get the same thing in a tune that's awesome but if its going to cost me 2 hours to tune it or whatever and I might as well just stick with this. Either way I like it a lot. But it would be nice to have it built into the software as opposed to an add-on

Most reputable tuners don't require additional hours to fully tune the car, it's part of the package. Between that and being unable to handle scaling for larger throttle bodies, you need to find a new tuner.

MT vs AT
 

It seems the most praise is from Manual Transmission owners. I'd like to hear from some AT people. ??

why? dey dont count :icon17:

I see no need for a sprint booster. Throttle lag due to heat soak can be helped with an oil cooler.

^^^ There's throttle lag even without heat soak and the SB cures all of that. Well worth the money and noticeable change out the box which is more than i can say for some of the others mods that get purchased for these cars.

Such a dickhead. People like you are why forums are dead.

You bumped a 6 month dead thread to throw out a keyboard warrior insult? Well played :rolleyes:

And this forum is doing just fine, IMNSHO ... all the questions have already been asked and answered, so there's no need for a lot of activity. The build threads are fairly active - there's some good stuff going on :driving:

lol looks like da newb was Own3d by mr. jar. :D

Everyone is a "dickhead" at one point or another. Plus without "dickheads" the forum would be boring...:excited:

Just ordered this, can't wait to try it out. I had no idea this even existed till I randomly came across the pic in Zbrahs profile that popped up at the top of the screen lol
