Well, originally I had a ppe standard tuner, and I set my truck to stock, then flashed a new stock file from the dealer, then flashed efi live. Unplugged trailer brake, no sound system, pulled all necessary fuses, lights off, doors shut, radio and AC off. Drove it and could barely even climb a hill. Talked to Willie Parsons from synthetic and I did a data log and he sent it to Kory at ppei. Kory said my MAF sensor was fucked, so I replaced it with one from O'Reillys and it made no bit of difference. So I unplugged the MAF sensor and it hauled ass, blew some black tho. Engine light has been on ever since I flashed it, and have worked with alligator performance and Willie and it still didnt work. I verified all my truck info was correct. I have 6 dtc codes displayed, including the 2 egr codes, even though I told them about the egr delete. Never had to fingerstick with the ppe standard. Also have Garrett stage 2 turbo. Maybe Kory didnt tune it right. Any help please?? This merygoround hasn't stopped for a month
