I'm back...I went for a road test, went to accelerate quicker than normal, the engine popped went into limp mode only 1/4mi form the shop. Thought I could limp back, but Nooooooo, it died. Friend happen by n pulled me to the shop. Found 3 fuses blown. Main relay, fan relay #2, and fuse block 12v feed, battery voltage was fine. Pulled plugs cause it was running like there were 3 dead cylinders. The plugs were black so I replaced them but no change. Hooked up the V2 and no codes. Now won't connect to the ecm. Beginning to wonder if this EFI tuning is for me!
