I'M LOOKING FOR SOME BASIC SCANTOOL READINGS . I SOLD AND BOUGHT MY 84GN BACK . IT RUNS GOOD TO CRUISE BUT FALLS ON ITS FACE WHEN I GO FOR FULL POWER . MY BROTHER (MECHANIC ) NOW HAS A SCANTOOL . WE ARE LOOKING FOR SOME INFORMATION AS TO WHERE WE SHOULD START ? THE ONLY MODIFICATATIONS ARE POSTON HEADERS AND 87 COIL PACK . WHAT SHOULD THE SCANTOOL READ FOR WHENEVER WE HOOK IT UP ?
