Supercharged C5 tune problems This problem started shortly after I got my car tuned back in October.. Thought it was possibly oxygen sensors so they were replaced. At idle and low rpm my car keeps going lean (like 18.xx on my wideband) in town from takeoff and just cruising it hesitates bad. Can somebody look at my tune and a couple short logs and give me an idea where I need to start?

just saw the file, it doesnt have 2 bar map sensor. At least the offset doesnt add up to a 2 bar.
Your o2 STFT are off, LTFT are on. If your fuel pump is still in good working order then get a another tuner.

The car isn't SD tuned and I have a 2 bar map sensor to install I'm just not familiar with what all I need to change in the tune to make it work correctly. As for the fuel pump it is a new pump that came with the A&a kit. The car seemed to do fine for the first week or so after the tune now I'm a little concerned about even driving it to another tuner because of the how lean it goes under light throttle
