Yep, sold my 2007 5.9 Cummins and bought a 2007 GMC sierra 2500 LBZ, so far it has an edge juiced CTS and i have a question, when i lay into the truck on level 5 i hit about 90 mph and the truck start to defuel, i know its the programmer doing it, anyone with the programmer able to tell me how to go into the settings and fix this?

I got it fixed, here it was my EGT's, when I got on it hard and when they hit about 1400 it began to defuel, I set the backdown settings to 1600 and havent had a problem since. And efi live will come after an airdog, dual CP3's, Twins and Larger injectors. And I need to find out what is done with the tranny so i don't waste money on a suncoast tranny kit if i don't need one.
