could this be the reason for crappy dyno relsults while taking a trip on the weekend Car threw 0121, 0141, 0200, 0300, and 0405 (hard fault), sent it to GM dealership and they told me today that my PCM fried, have been throwing 0405 and 0300 since i got it back from the cam install. not posotive but if 0405 code throws, It just run off TPS and what the car knows, doesn't recognize the tune right? Here are my questions
1. could this be the reason why my dyno number are so low.
2. shouldn't a good tuner realize that that it's throwing these codes.
3. during the tune he told me thast no matter what he did with the timing or fuel it was only 1 or 2 HP difference.
