I have the car tuned for 91 w/a C&L cai from AM. 91 tune and cai work awesome. went to move up to the 93 tune and the car kept throwing lean code for bank one and two. Called AM had them check the tune files and sent new ones. Same issue. Any one else have any problems with their tunes?
Yes I know i should take it to a shop and have it custom tuned but im waiting till after more parts go on.

well, knowing they haven't changed the air fuel at idle, it's possible that they have the wrong MAF Transfer Function programmed in there.

Thanks guys, I'll call them back again and see what they want to do this time around. You know what they say third times a charm.
