Re: pcm adjustment
I sent my pcm and harness to someone in CAl. They ask my for-tire size. rear ratio and other things. Got it back in the mail. hooked it up and that is all I know. they programmed 3.07 instead of 3.70. I called them at the time they said drive it and if you still want it changed call us. I did no response. There's got to be someone out there I can send my PCM to that can make this change for less then a full tune.
