well ok iam trying to see if this makes any sence. pcmforless sales a 85vette, chip but not the 85 iroc chip. i thought that all 85 ecm's were the same for the tpi . i know in 86 they upgraded the ecm, but did they do this in the vette in first? the funny thing is that when i first made the 305 to 350 swap, i bought an 85 vette chip and the car runns fine. now i have upgraded my cam and intake and i need a custom tuned chip.

thanks for any help,
Mike
