Official Sprint Booster feedback thread.
Between 1-10, 10 being the best, I give this mod a 9. I would have given it a 10 if the price was lower. It has to be the most expensive piece of plastic I have ever purchased.

It was well worth it though.
Glad that you enjoyed it....have fun !
has anyone else noticed this?
Oh, don't get me wrong - the Sprintbboster still works great and the sluggishness is reduced even after weeks of driving. I'm just saying that a reset is still needed. Don't take my word for it. Drive your car with Sprintbooster installed for at least a few weeks, including in traffic, without doing a reset. Then, after driving it one day for a bit, perform a reset and immediately go for a drive. It is very noticeable! The Sprintbooster does not stop your car from "learning" your driving behavior.

I removed my Sprint Booster from my car. Not because it's a bad product, but because my car behaved like I was drag racing from almost every stoplight. It accelerated too quickly for my taste. It was like I was on a roller coaster
; the throttle is very sensitive. Or I might just have a heavy foot.
Before I had the Sprint Booster, the throttle response was already pretty darn good. I never had to manually shift. If anybody in LA or OC wants to try it out, they can let me know. I'm probably going to show it to some people and see if they want to try it on their cars. Otherwise, it goes up for sale on ebay.

Even with the ESP on, it lays scratch pretty easy.
The whole reason, I like HP is for the feeling of acceleration, which is easier to access, around town, with the sprintbooster.
just installed mine
what can I say that it's not already been posted........
I'm so happy I can't believe it
Can't wait to take my 0/62mph time because the feeling I have is that now I should be somewhere near 4,7 seconds
Best money ever spent on a car!
