I was hoping someone would reply to this as I have the same cam. 08 H3 Hummer with a 2019 6.0, with Truck Norris Cam. E67 pcm. Your scan looks exactly like mine. I can get the SD/Maff tune good, it's the Idle that is kicking my ass. I used this thread and it did NOT work for me. It's like it doesn't respond to timing and every time you adjust, the AF ratio goes to hell. https://forum.hptuners.com/showthrea...&highlight=e67
