Another Sprintbooster review
 

Review is for A/T.

I know it does not impact horsepower or torque.

Really makes the car more responsive in a way that seems different than just pushing harder on pedal. Definitely like it. Will probably keep it on sport 5 mode which is about the 1/3 overall setting. Tried race mode 6 ... Tach jumps quick, but it'd get old driving in traffic.

I really like that in parking lots it's as if it's off. You can still drive safely with light accelerator pressure. In fact, seems like no difference than being off.

Install was okay. Just Couple steps but prying that cover plate off took a little working as you need a real thin flat head.

Understand there's a lot of controversy about Sprintbooster on our forum. Not trying to resurrect that ... Just saying it makes a fun car more fun IMO.

I had it a couple of months. Didn't really like it. I hate it the dead pedal feel on red mode. It also felt too touchy. Just get a tune

A sprintbooster is the best temporary fix until you have enough mods to get a tune. The stock throttle response is unaccecptable. Ive driven my fair share of sports cars and the throttle response should be touchy/sensitive IMO. The SB gives the 370z throttle response the character it was suppose to have from the factory. Its a temporary fix buts it wayyy better than the throttle response you get from the factory.

:iagree: and that's a couple grands in the hole before one is ready for any tuning. Plus another grand if you do it right and go for a dyno-tuned. Simply put, the sprintbooster works as advertised.

Every stock or mildly modded Z should be running with this...until you're ready for real power, then it's FI time! Trying to maximize N/A power is laughable! we can't break 290 lb ft in torque with full bolt-ons and tuned! :rofl2:

Sprint booster keeps you in warranty so....
