89 IROC ECM#?
Anyone know where I can get a stock GM "chip" for an 89 IROC 5.7, auto? Can anyone tell me the part number for this "chip"? Thanks. My "new" IROC has an aftermarket chip in it and I want to return it to stock GM for now. Thanks again!

AUJN is the code for a stock 89 350 with dual cats and 3.27 gears. GM just raised the price however from $50 to $300.
