Recently i have notice higher than normal EGT's. This is not related to temperature because it was hotter a few weeks ago and the EGTs were cooler then than they are now with it bein 15* or so cooler. Today i was messin around and mashed it from a stop in extreme and my pyrometer was at 1400 before i hit 80. It also has been taking forever to cool off for shut down. Sometimes after normal driving i have to sit there for 5 minutes or more for it to drop below 350.
Also i checked it for codes and there was 2 in there for boost pressure, one said boost pressure low, and the other said boost pressure not detected. We had it hooked to an SCT with live readout and in extreme while my boost gauge was reading near 28, the sct only showed about 12. When i put my boost fooler in i had it set for about 20 PSI.
I noticed the EGT issues within the last few days. Im guessing its just a coincidence but it seemed to do after i put on my stack. But i would think the stack would lower EGTs as it no longer has all the bends going over the axle.
What do you guys think about all this?
