I have a 2006 GMC Sierra Crew Cab, High flow intake filter, with cut out bottom housing on intake to turn it into a CIA, with PVC Piping for intake tubing (helps).
Super 44 Muffler where stock muffler was, with a turn down echo tip.
I have provided the tune file and the log from this morning. Seem to notice I have some KR. The tune woke my truck up alot, and gave it good amount more power... But it loves fuel now, and im running Supreme aka Premium. Any tips I should do to the tune, oh and I will be installing some headers within next few days. Thank you to all in advance!
