Have you guys heard of Sprint booster

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?

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.
