I just got my headers and y pipe installed this weekend. I have a cam also and had it tuned with a buddy. My question is sometimes the TCS will turn off by itself and you can not turn it off or on. The seat adjuster switches will also not work. It never did this until after the cam install. Could there be a tuning issue or would it be a damaged electrical connection somewhere due to the install. Another issue is the rpms seem to hang up sometimes when I rev it up and it won't come down for a sec or two.

Sounds like a problem with the BCM (body control module) - the TCS switch goes through the BCM, and I would guess that the seat adjusters do as well. I'd trace the wiring for each of those systems and make sure the wiring is OK.

Tuning the PCM should not affect the BCM.

with all the work going under the hood i wonder if the ground from the body to the eng. was reconnected or torn off. that could also explain the throttle hanging up if it's using the cable for ground, it's tring to weld it's self togther

That's a really good point.

thats one i learned the hard way,after an eng swap i waited 2 days on a shift cable i welded together.


although the intake is composite the T\B is grounded. see the pdf it has all grds in the 100s (underhood)
