Message: [QUOTE="windrunner408, post: 185459, member: 1868"] Yea I can't monitor the second IAT sensor with my CTS. I have thought about replacing both the CKP and CMP sensors and might just do that next week. Not sure what you mean by this but the egr is totally deleted and I dont even have the valve plugged in and I have the egr valve disabled with the SCT tuner. On a side note guys, what I have noticed before was the MAF (IAT1) sensor would be displaying IAT and it would trend at 2-4*F below OAT (I should note that IAT changes in 2*F increments) for about 10 miles or so while the truck as at normal operating temperature and then it would just jump to like 6-10*F above OAT. I am not sure what the deal is on why the IAT would do that but perhaps the MAF sensor is damaged from all the times I have removed my intake from the turbo and somehow interupts the signal to the ECM and sends it into limp mode. I am not saying this IS the case but am just throwing out a suggestion. I however could not get the IAT to jump yesterday when it raised the boost level. [/QUOTE]
