    C-kit upgrade from B-kit

    Can anybody even guess!

    With my current set up I see 83.5mph @ 8400rpm. I run the B-kit SC with all the other good bits. Can anyone even guess at what sort of top end difference bolting on the new C-Kit SC which produces approx 1-1.5lbs more boost at the same rpm. I will need to repitch to get/keep the rpm's back down. Or I could run upto 8600rpm?

    Looking for 85mph?

    On my turbo setup, pretty consistently I'm seeing +1 mph from +1 psi boost.
