It's amazing this truck is still kickin'. It got broke-in wrong, under-maintained, over-weighted, abused, and Now I have it with 108K hard miles on the complete truck, and it's having to pump ~450HP daily.
I think high Peak EGT is different from Sustained EGT,, I personally feel 1500* for 5-7 seconds will cause little or no harm,, Look at the Sled Pullers,, I have heard some of them get 2000* pulling the sled,, Even drag racers can get 2K*F
As a personal opinion, 1250* pre-turbo should be nothing to even consider, and 1300* shouldn't force you to get passed by a PowerJoke.
