I hope I can find some help here once again! I'm outside of Durango CO on a family trip towing my fifth wheel and have no HP between idle and 2000rpms in fact I had to back down a small hill to get a run at it, not fun. I have noticed this after I installed a efi live tune from Idaho Rob but all other areas the truck runs great. I have the banks cold air intake with the bigger mouth piece, bigger exhaust, egr block off plate and the Edge CTS monitor. I'm hoping someone can tell me where to start looking? From what I read it sounds like my MAP sensor may not be scaled correctly because you can give it wot and it doesn't smoke. I plan to call Rob tomorrow morning and talk with him also. Thank you, Jason
