02 lightning running real ruff after 93oct & pully tune

[stangster666]

i just loaded the programe on my truck ot was the 93 octain and pully tune with the mods of obdiII off and both heat banks off. and now my truck is running really bad the idle drops low then rises the truck shakes and is running really rich. i tried to put the stock tune back on and it said it loaded and nothing changed as far as the truck running any better. so i reloaded the programe then disconected my battery for 1 hour then reconected it and still no change in ruff running condition. if you could please help me i would greatly apretiate it i am supposed to run on the show pinks tomarrow morning down here in florida and if my truck isn't running right im screwed.
