Stock truck - 15-17lbs of boost
EGT, 1250 sustained, short bursts over that to 1400 is fine, but nothing sustained, if you are cresting a hill and egt's are at 1250-1300 don't back out stay in it, once you top the hill it will cool down quickly. It takes over 2 min to heat soak the pistons.
But if you have proper air flow and exhaust you should be fine.
Trans temp, if I see over 200 sustained I want more cooling, if I see 220 I am pulling over, just so you know Ferd considers anything under 230 normal. Normal trans temps run 70-90 above ambient, 70 when unloaded and 90 when towing. I have found this to be accurate, it will also take up to 20 in to register on the gauge as that's a lot of fluid to heat up. I hope you got the trans gauge that starts at 100, depending on where you live and the temps you may not see it move til spring!!
PM me with any ?
