[QUOTE="Wayne Foy, post: 551252, member: 60582"] its possible that it was tampered with. If you put the ST in neutral, rev the engine. If it goes over 3100 rpms, you have been chipped or flash tuned. As far as rev limiters, there are actually 3 in the programming. 1. Neutral Limit - set at factory to 3100 2. RPM Vs Torque - limiter hits once you reach a set RPM, Factory rev limit is set at 6250 in gear 3. Speed Vs Torque - limiter hits once you reach set speed, factory speed limiter is set to 94 mph on 04 KRN0-KRN2 PCM codes. I know my 04 ST stock would shut down at around 98, so thats the amount my speedo was off from the factory as well. There are variables of the above I can adjust for situations, like a 2 step drag launch, but besides that, those are the mains. [/QUOTE]
