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.

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
