when my rb25 swap was done the car ran great...no problems what so ever and the SAFCII install wasn't a problem either
a week later and the nismo adjustable fpr came in and threw that on and retuned the safcII slightly and the car runs even stronger. i knew i needed to upgrade the fpr but i didn't think it would have made that much of a difference.
btw, i'm running the greddy intake manifold....makes it a hell of a lot easier to work on the engine
