detjoe Posted April 12, 2008 Report Share Posted April 12, 2008 Your playing with fire,but I am sure some of the hptuners pro's can help you.Did you post on hptuners website? be safe young jedi...the hptuner force is not to be taken lightly. after you change a tune, it will take some 'learning time' to fill in data into the PCM, so it might just need some time...or you could be destroying your engine.

Fireman31 Posted April 12, 2008 Report Share Posted April 12, 2008 You have it set to idle 600-700 but it idles at 300 at times........either you have something totally incorrect in the tune you wrote or your alternator is going bad.
