I'm Upreved tuned and let me tell you it does compliment the throttle response.

Alright guys, I got a call back from my service dept. Apparently our cars cut power pretty early (before 220F). Nissan Tech-Line says the car actually cuts power because of oil temperature. It's not surprising, but it's disappointing because I thought the ECM would cut power after 220F.

As a personal preference, I'm fine without SB as the response isn't too bad when the car is under normal operating conditions. However, an oil cooler and moving to FI will offset this "power loss" ;)

oil cooler and hypertech:tiphat:

To those of you who have installed SB: Did it affect your gas mileage? Just curious...

Their 30 Day Money Back Guarantee has a note:

No questions asked! NOTE: Group buy, coupon code and wholesale orders do not qualify for the 30 money back guarantee.

once you have it you dont wanna get rid of it. i drive on race mode daily and never been happier about the throttle response.

Not at all man!

I hear what you saying, but would be interested to know if anyone returned the SB?

I have an AT on the base model and find that to make a quick lane change or to pass a car on the highway, I have a lag then a surge in acceleration. NOT GOOD!!

for 300$ dude vs 1000$ for a tune and according to some members even with a tune they still get this crapy lag! im getting my Z tuned in spring and im keeping my SB. once in a while i turn it off to feel the difference and man im happy i got this lil gadget!

Good Info...I think I will give it a try...THX

I just ordered the unit today..Do you generally keep it on Sport or Aggressive mode all of the time or only switch as needed?

Switch as needed.

Does it stay in which ever mode you set it in when you start the car the next time you drive?

Yes, it will remember the last setting you had it on. You can even remove the modulator and it will still remember. On that note, I woudn't put it somewhere you can see it, because the light is fairly bright, and your eyes will be constantly drawn to it. I ended leaving it on the most agressive setting and tossed it behind the middle console.

$1000 for a tune nononononono. Dyno and tune for 550 at stillen.

yes!

yeah too bad we dont any of those around here lol well here i need the cobb access port 400 some $ plus the dyno tunning 2 hours min like 300$ at Lentech in Ottawa. ill get it done but the SB keeps me happy for now :tup:

ya man that kinda sucks for you guys. Thank God we have stillen in So Cal. I guess things back east can be more expensive.

Now I hear people saying they have lag when they step on the gas, my question is what rpm range are you in when you do this? I find that if I drop a gear or two, just like in a stick, my acceleration is good. Yes if Im in a low rpm range and floor it, it takes a sec to kick in like any car Ive driven.

My next question is, does the SB take the lag away at all rpm ranges? If Im at 2k rpm in 6th or 7th gear and I floor it with a SB, will there be lag?

Here is a white paper I found that seems pretty well documented and backed up.

If the SB does more than just amp the sensitivity I invite them to state how for us. So I guess the real test for the SB is, is it still faster when the gas pedal is floored as fast as possible? I can see the response when you dont floor the pedal as its amping things but WOT is another story.

In the paper he mentioned a tuner changing the pedals scalability so I wonder if this is done when we get our tunes?

i was a sceptic at first.. thinking meh, just another snake oil application alongside those sh*tty fuel-saving magnets bullsh*t but after sat in my fren's civic type R with sprint booster installed...boy was i blown away!! really eliminates any delay, response is spot-on immediate!! I'm totally sold.

To those who are still a sceptic, go sit in one and see for yourself.

there are many reasons the sprint boosters seem to work well, most of those reasons are stuff people don't think about really, first off there is the placebo effect just putting the thing in will make you think it is improved, then there is human lag time, between you thinking about putting the pedal down and your foot actually doing it there is over a half second of lag in your own brain, also most people don't just slam the pedal down, so there is lag there. people with better reflexes, a stronger ankle, and a better feel for modulating a gas pedal will have less lag.

The only real reason to buy a sprint booster is if you desire a shorter gas pedal travel, because that's all it does, it shortens the pedal up electronically. pushing the pedal down 75% with the sprint booster on is the same as full throttle, the last 25% of the pedal stroke means nothing so all it does is shorten the time it takes you to actually push the pedal in all the way. Some of these pedal tuners actually increase the throttle percentage while depressing the pedal but once you stop pushing it in farther will ramp back down to the real percentage so say you push the pedal from 25% to 80% it will tell the car you pushed it in 100% while your foot is moving and then drop back down to 80% once your foot reaches it.

To actually increase the cars responsiveness(instead of your foots) you need to do things like tuning the acceleration enrichment, the ETB logic, the spark maps, the rotating inertia, the torque band, and things of that nature all of which cost a hell of a lot more than $300.

Anyone know of any group buys for this thing?

don't buy it, just floor the damn thing, our cars have over 280rwhp!!!!

It increases throttle response. Just like pushing the 'M' button in a Bimmer.

yep still lovin it!!! always driving with Sport mode, a lil hard on my rear tires but hey its a Z and its built for that.

Car would not start Sprint Booster.
 

FYI - I tried installing this device in my 2011 Z and could not get the car to start, so I returned it. I don't know if it was defective or what? I did have trouble getting the cable connector to seat properly; it would not snap into place like you would expect, and I did not want to apply too much force because of my fear the CHEAP BRITTLE plastic might crack in the process.

Honestly, my perception of the Booster is that it's very, very, very cheaply made. I was very disappointed. The plastic case they use can't cost more than 10 cents. You would think they could do better for the $300 dollars they charge.

Nice review!
I want this system!

I had the exact same issue and view on the product. Anyone can tell it is cheaply made, and the design is generic, so it doesn't fit like it should. My car also would not start when installed, but it started right up without it. I informed the vendor, sent the bad one back, and waited for a new one. Although I had to go through all that, I was happy in the end. Sure its cheap, but it works, and I haven't had any issues since.

Send it back and give it another chance. You have 30 days to send it back for a full refund if you aren't happy with it.

This device addresses and improves one of the weakest links in the chain of driver to car to road: the right foot.

If you want no lag, downshift into whatever gear will put you at 5500 RPM in anticipation and then floor it. Use SRM if you need to and try to tell me there's a delay trying to push it through that yellow light. There's only as much lag as time it takes you to downshift. AT folks - maybe this is a good alternative to having to use manual mode all the time.

A very experienced driver can essentially do what this device does by varying his driving methods. But the fun factor of a device like this makes is perfect for some people. I would akin it to SRM for someone with limited or no heel-toe ability who wants to track. I would definitely like to test drive a car with SB to see the difference.

So it does not increase throttle response, just pedal response? Then I guess you could get the same result by driving harder, or fitting a spacer into your pedal.

:iagree: I just don't get the "slow" or "lag" throttle issue. Never had it with mine.

I may just trial one to know what it's all about. I'll happily post a thorough review. Feel free to Paypal donations if you're interested in supporting the cause :).

Not sure if this matters but I have an auto and it does make a difference, car does respond better and I do notice an increase on fuel consumption, just my two cents =P

I'm glad to hear someone finally admit that gas mileage isn't quite as good with SB. It makes sense if the car is driving more aggressive after install. It is like driving more aggressively w/o SB - you just don't have to push the pedal as far.

With an AT you have to be in manual mode, but you can still alter your driving to do exactly what this device does. As I noted previously, this could be a good solution for those of you with an AT who aren't interested in manual mode when you want to get on it. With SB you can just switch to Sports or Race mode and still keep it automatic.

seriously ive been driving with my SB for almost a year and didn't notice the extra gas consumption.

^ Same.

I spent 5 minutes reading this thread and bought it. Love it! My previous car was a srt8 with 650 hp. After purchasing a $600 throttle body the car finally had the snappy throttle response where you could modulate the charger kicking in instead of the gas pedal being an off/on button. For the price of this unit this little doo-dad does the same thing. The price for throttle bodies for the z are quite high so the sb cleaned up response nicley for 1/3 the cost of new tb. I am aware it doesnt give you any more performance but its fun to drive now!

Is there still not a cheaper alternative/product that does the same thing. The reviews I have read on other forums all talk about how cheap these things appear to be. My last car was a bimmer and I always enjoyed the sport mode.
