[QUOTE="exdeath, post: 8973131, member: 56343"] First you need to confirm if it's a real or false condition. If you don't have a wideband or something you might try swapping the O2s. Log MAF, fuel pressure, and battery volts and see if either of them suddenly drop or flatline during a moderate pull, and see what fuel trims are up to. In the meantime don't abuse it or give it boost until you know for sure. If everything checks out and it's the tune itself, you can add global fuel to the tune, but if your tune is that bad to begin with I would go back to stock (since you don't have a pulley/MAF/injectors) and seriously consider another tune. Unlikely that it's a gasket or something if it started right after you installed the tune; the light doesn't come on right away, it takes a few cycles and attempting to compensate before it finally gives up and trips the light.
