Just curious if anyone on here can do email tunes for my truck. I have an MPVI2 and the only mods I have so far is a cold air intake and E85 Flex Fuel kit with a sensor that needs to be activated. The most important thing I'd like however, is deactivating Active Fuel Management (AFM) due to concerns of the notorious GM lifter issues these 6.2's and 5.3's are experiencing. Lastly, a "fine tune" after the first tune. I'll provide the datalogging with a 20-minute drive of cruising and some WOT accelerations.
Let me know. Thanks!
