Stock truck EGT...look right?
Only "mod" I can think of that would change EGT's are my 17" wheels and tires, maybe a fuel filter change. I haven't seen any sort of tuner or chip on this thing.
This was taken going up a pretty good hill, giving about 50% throttle. It just hung at 10PSI/1100* (picture). I tried to do a video, but was in the wrong mode. When I gave it 80-100% throttle and it down shifted, it pegged to about 18 PSI boost and my EGT went to 1300 before I left off at almost 3,000 RPM. It would have kept going had I let it.
