Took my 84 ttype out for a spin today. Car started to sputter then it stalled. I got it home took the stock MAF off and replaced it with the 87 MAF. Do I need to put the 87 ECM in as well? I don't have an chip at the moment for the ECM will this be a problem ? Once I put the 87 MAF now I can finally hear the turbo spool and it didn't stall out.
