I had thought I had the 110 mm JLT intake and so I had Am/bama tuning write tunes for that intake. The car runs great and after the cam install, I wanted to check my A/F which was spot on at 12.7/8: 1. I had the diablo shop also write me a tune but after loading into the car, it would go into fail safe and shutoff. Chip, sent me another tune but it did the same thing. He then sent me a tune for the 88 mm and that tune works great. I wonder my Am/bama tunes don't go to fail safe mode with 110mm intake?
