sorry to hear your having problems. did you download the Extreme Tune software? if you did you can adjust idle speed, also a/f, etc. BUT it sounds like those adjustments would only be a crutch for your tune. is Wayne sending your tunes via email, or are you physically sending the sct back to him? if its through email like mine you should be able have it revised by him very quickly.
the tune saying performance fuel ( or whatever) is just a name he put on the tune to diferentiate from the others. if you have the Extreme Tune software you can change the name of tune yourself to whatever you want. im sure its not n "off the shelf" tune. your mods are unique.
