Hi kyler3325t,

If the engine has been tuned already the quickest thing for you to do is go to the FUEL MAIN tab and go to the MASTER FUEL TRIM and enter -30.8% and this will reduce the fuel trim back and allow for the increase in injector flow.

If this engine has not been tuned be warned this suggestion will work for a previously correctly tuned engine only.
