Hated the 5* so much I sold my tuner even. Driveability on the truck was terrible tuned I found, no matter what octane program I chose (I had 3) and ran. Had them recompile the tunes a couple times as they F'd up the first one and my grill shutters never opened, and then I randomly shit a wastegate solenoid, and then just found the truck drove like ass.This quote is hidden because you are ignoring this member.
