Just installed a 2.8 Pully with a tune from leathal Performace, I also installed a AEM air to fuel ratio gauge, seems to be running a bit lean, just wondering if anyone else has delt with this?

I trust Lethal Performance, but would always have a person with experience do a dyno tune when adding a pulley. There are too many variables to account for with your engine that you may need a small tweak.
