I do not have an eprom. I know that 650's with just an SAFC makes it difficult to tune. Because you subtract so much fuel, and the ECU goes to the map for that amount of airflow, and your timing becomes way off from where you want it to be.

So I read that for the 1g guys upgrading to the 2g maf makes it pretty much a bolt on for 550's. I think -24 for 550s +22 for 2g maf. Something like that. So I was thinking... Going with 650's on a 2g maf would be like tuning for 550's on 1g maf. It would be easier. Get what I'm saying? Am I thinking correct? Has anybody done this setup before? If so, good results?
