There is not an "ACCELLERATOR" limiter per se. There is a rev. limiter which cuts the engine at 6,300 +/- rpm, to prevent you from turning it into metal shavings. And there is a top end speed limiter which cuts the engine at 155 mph.

Chipping your car should increase the rev. limit by 1,500 rpm +/- but they will not remove it completely. As far as the top end speed limiter I don't know anyone who is effected by being limited to 155 mph. Even on the track, the car doesn't have the ponies to reach those speeds even on the lonegest straightaways before you have to start braking for turn one.

MBEPIC is right. (1) Aftermarket Exhaust for sure. $650.00 (2) Aftermarket high flow air intskes. $80.00 (3) Aftermarket ECU remap. $600.00 (4) And Racing Suspension $700.00 (IMO Very Important) is all you'll really need for 25% improved performance.

Have fun
