Dave Kriedeman Posted November 24, 2015 Report Share Posted November 24, 2015 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.RegardsDave.
