I am wondering what PSI I should be running at while at full throttle with this engine. I have P2P at around 4" running a 24" Raker HO to 5900 RPM at 35 PSI loaded. I am getting a mysterious exhaust temperature fault code from time to time but engine is not running hot at all. I would think I can raise engine some more as 35 PSI is pretty high but I cannot figure out this alarm I'm getting-it is code 136 for what its worth. It is going into the dealership next week when the lead mechanic gets back from mandatory training. Does anybody have any ideas?? Thank you!
