I have a 06 lly and installed a Bully Dog GT programmer for the lbz. It allows the defuel settings to be entered manually. I would like to know what are the safe settings. Currently the truck runs great but want to make sure i'm not going to hurt the engine or trans. There are no other performance mods done to the truck.

 

egt's should be set at around 1300*
boost you could probably set at 32-35psi and be safe

 

Max sustained egts can be 1350 degrees,, for short bursts (less than 30 seconds) they can be higher than 1600
