...and next time, think before you decide to add more timing to a tune that is likely already running as much timing as will make power...

RE: Running Too Lean?!

Im having the same problem, although I didnt mess with my tune at all. I had a C&L street and a brenspeed tune. Rougher Idle, and rich fuel smell. I took off the C&L and swapped it for my K&N with the stock tune and I got P0171 after a few WOT. The only other mods are magnaflow catted x pipe and slp loudmouths. If I put on the stock airbox and leave my exhaust on will I have a problem at the dealer?
