High EGT on stock truck

[Dr.Kayak]

I finished my gauge install and went for a test run up into the Sierras. Climbing a good hill at WOT the EGT climb right thru 1300. I was at 4,000ft and it was 90 degrees out. I caught up with traffic and had to let off before I could see how high it was going to go. Is this normal for a stock truck? I’m a little concerned that I have pushed it well over 1300 on previous climbs, before I got the gauges. How firm is the 1300 degree rule?



Under normal driving the EGT looks OK. I’m getting 19lbs. of Boost at WOT.



Real satisfied with the A-pillar setup.
