Still putting all my new upgraded goodies into my 85 GN!! Holy shit money doesnt last long with one of these cars!!!LOL! But anyway I have one question I installed my new 86/87 ecm and new tt chip but I left the 86/87 calpac chip in it. Should I have put the calpac from the 85 ecm into the new ecm? The car runs fine without doing this but I have only started it twice since I put some of the new parts in and never drove it on the road yet(too much freakin snow!!) Any info greatly appreciated. Thanks Steve
