I just got a cel about a week after installing the tunable induction kit and the 93 tune with the sct xcal 2, just curious if anyone else has had any trouble codes pop up, I had 2 a P0170 and a P0174 left and right bank running lean. So I talked to Dave at brenspeed (really nice guy and very helpful) and he had me reinstall the 93 tune again and the CEL was gone, told me to drive it around for a couple of days to see if it would happen again and that if it did he would have Brent e-mail me a richer tune.
