I was thinking of doing a similar setup cept stock tranny components for now. But I have a SAFCII and I wanted a tune the difference for me is I have HKS 256I and 264E Step2 cams and I was looking to upgrade to a 2871R now if I get a tune with the stock t28 with a SAFCII would the same thing apply to me if upgraded turbos? Would I have to get a ROM Tune? Can you have a ROM Tune and a SAFC tune at the same tuime or do you eliminate the SAFC?
