i had him do a rear o2 delat tune when he was here in southern californal when all i had was my fwi and my speed daddy headers he had done some small changes from a tune i had done in denver so it was fine but he forgot to take off my speed govener and he fixed that and modified the shift tables and emailed me that tune but didnt have it set up for my cam or my injectors so i modifed that myself when i did the install.. it wasnt a wideband tune that he did but it did run better than the one i had done in denver when he was done! good guy deffantly knows his stuff!!!
