Sorry I didnt see the rest... I have hypertech programming. I also have a few mods. CAI, UD pulleys, MSD Coil and Wires, TB Spacer, X pipe no cats, Upgraded clutch.. umm i cant think of anything eles right now.

Tac2cul

well remove the hypertech if you can and put it back to stock settings and see if that helps.

What ive found so far is a P0605 constitues a PCM replacement so i would try removing the hypertech and going from there

I figured that had something to do with it. I have a friend who owns a Rebuild shop and he used his very expensive computer to read it. The fan came on but then went right off and thats when it brought up that code just after that fan turned off. I can also change the CCRM because I got another one and it might be bad.

i would remove the hypertech and give it a shot....

if all is well after that reinstall da hypertech and see if it helps...sometimes chips hiccup

the hypersuck tuner gives out random codes when its installed. put it back to stock and rescan it. then get a diablo or sct

Lose the CrapperTech Tuner. It will actually make you lose power. Get a Diablo.
