    Approx. 1 MPH & 100 RPMs more, and a leaner AFR with the S3 over GW.

    Are you running an external IC?

    I think the rrfpr is probably the best way to get optimum mixture control, both at idle and wot. If your upgrading then by all means go with the "X".

    Close to the same PSI. Riva is higher by maybe 1 psi (give or take), but it pushes a higher volume of air. Remember, the GW is a drop-in 127mm wheel. The Riva has a custom machined front housing to fit the taller S3 wheel. I ran the S3 with XS IC and Riva rear air intake with 42# injectors and my exhaust manifold bell is in perfect condition still.

    The S3 will be ok with 42's only if the stock IC is in place.

    48s should suffice with an X charger, but it will be rich on the bottom.
