my 86 t came with 2 chips . I dont know if either were stock. One is made by applied engineering and says "pit bull" on it. the other says B.O.M. any idea what these chips change from stock.confused:
Well, the stock chips were bad enough with their relatively high timing, the Pit Bull chips were FAR worse. Technology has advanced FAR beyond those chips. Never heard of the BOM chip. Modern day alternatives are FAR better AND safer.
