I'm on my desktop now, and going to look at it. From my initial glance, you were running ALOT of PW, and very little timing. Also it appeared the limiters were still stock which is going to prevent the timing from going up where it's commanded, and you were calling for ALOT of torque in the throttle table, so much so it is maxxing out at 80% throttle. I'm going to take a closer look at it, but a 2500 PW is going to run fairly high EGT's anyway you look at it.
