Hi everybody,
New to G8Board. Had my car for two years now, just started getting into "playing" with it. Bought my '08 GT used. Previous owner put a magnaflow on, and recently purchased the Diablosport In-tune and a Volant CAI. Been running 93 in the car, never had an issue, never a check engine light. Installed the intake and diable tune a week ago. Throwing two codes now P0171 and P0174. It's running too lean, which makes perfect sense. I've messed with the tuner a bit to try and get more fuel into the engine. I just don't want to keep dumping more fuel in there without knowing what I'm doing. Does anybody have this tuner or know what the settings should be? Appreciate the help.
