I run my 08 GMC 3500 with a PPE hot plus 2 ET. Factory intake and exhaust. I recently pulled my Black Thunder to missouri from Texas running 75-80 all the way. I ran th3 3rd setting at an extra 125hp. Not one problem. Same thing on the return with another BT. Ive had great luck with PPE stuff. Never a code set or any problems. Oh yea, the DPF is still on and active!
