I have an a4 01 c5 with a TRaK cam and other bolt ons that has been dyno tuned already for 387rwhp. If I add a FAST 90/90 setup, will I need to have it re-dyno tuned or could I just have it dynoed to see the #'s I get? I would rather not do it if it is going to cost $500 just to dyno tune with an intake addition. Finally, what kind of #'s could I see?

Most shops only charge ~$100 for a retune.

You can get away without a retune but you'll be leaving some power on the table.

even if it was tuned from thunder racing and I go somewhere else? If so, that is a good thing for sure!
