Thread: Factory PCM with no speed limiter??

I tried to see when my car cuts out and it doesn't... What is the speed limited to on an '04 GTP... I haven't put an aftermarket PCM in it yet... I'm confused...

150 is the stock speed limiter.

nah mine does about 125mph @ 2800 RPM's (obviously 4th gear lol)....erm then it cuts back/off or whatever.

142 on the comp G. i aint done it but thats what i heard. ive dont just about 140 stock

There are other things that will effect the cutoff, but the max speed set in the PCM is 150. There are injector cutoff limits lower, though.

Picture is worth a thousand words.

yep good SS

Well I don't have a CompG and I was going well above 125

Here's an 02 GTP PCM so you can see the difference.
