Get the PCM reflashed, or purchase one of the many "buy and play" tuners on the market.

Can one of these remove or change the speed limiter ONLY without making any other changes?

Also, can a dealer detect that the speed limiter has been removed or changed?

Thanks!:cheers

1. Probably so I'm assuming.
2. Maybe so...not sure. If you have to take the car in for repair work, just reflash the ECM with the stock program.

Others will have more input on this than I.......sorry.

Question: With the Predator tuner, for example, when you reflash the computer with the stock program ("going back to stock"), is there any remnant of the Predator program left in the PCM? Will the friendly GM dealer find that the PCM was re-flashed and try to void the factory warranty?
