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?
The 550's NEARLY balance out for a 2g mas swap. We have discussed this before on this forum...try digging around a bit.

The 650's work okay on a S-afc..I would recommend to just take it somewhere to get tuned. I charge $150 to setup S-afc's and tune them for high/low.
