I am only wanting to take the 4-cyl. shit off the truck. I would get the BB tune, but i want to be abe to return it back to factory if it has to go in for warrenty work. Im not looking for any performance gains, i just want the AFM off so i can get my exhaust put back on . I had magnaflows on it before, and it sounded like shit when it dropped into 4-cylinder mode while i was in tow/haul pulling a trailer. So i got the factory exhaust put back on....Pretty much a waste of $400. So now im trying to find the easiest and most cost effective way to take AFM off, and put it back on...Any suggestions?? The truck is a 08 silverado 4x4 with the 5.3
