Have you guys heard of Sprint booster

Sprint boosters work. Depending on the setting, it reduces or eliminates the electronic delay when you press your accelerator pedal. As cars are now drive my wire, the manufacturers purposely put a .4-.5 second delay on the accelerator as a "safety" devise so the car gas pedal does not feel jumpy. (It mimics the old gas pedals that were drive by wire.)

With that said, the effects of a sprint booster can also be achieved through a tune and reprogram of the ECU.
