hey guys, so purchased my 06 3 weeks ago an noticed the p0171 code. exhaust smells rich but it claims lean bank 1. Mods( Cam, Intake, Air Intake, LTs, Magnaflow with cut outs(closed). My guess is its got a tune on it because it runs great. Thats about all I could dig up on it. The rest is like I said Mystery car. Any ideas? ( dont thrash the noobie too much hehe)

If this was diagnosed by a technician then they should know the source of the problem. It could be O2 sensor or injector problem or even the tune could be bad.
If you have not taken to a tuner then I would look for one in your area who has a reputation of being reliable. You have several mods to the car, so a dealer is not the place to go.

Watch the O2's in real time and you should see the difference between the banks. lower Mv is lean. Hope this helps
