Good to see another 6.0 around! Which programmer did you install?
As far as your EGTs, I would try to stay under 1100 as much as possible. I personally have hit 1400-1500+ but only for short amounts of time. Normally when cruising I am around 700 or so. I will hit 1000 when towing, but haven't had an issues with my truck. Are you running stock head bolts, or upgraded head studs?
