Default would i need a retune immediatley after a ported stock intake/TB

the car has a halltech 103, kooks LT, catless X, and bullets should be here soon. question is...if i get a ported stock intake/TB should i get it retuned immediatley? how much power is this worth? and how high in the RPM band does the power start showing up?

What if the car is bone stock, stock tune, with only an MF103 CAI...would adding a ported stock intake/TB then require a tune?

From what I've seen, just porting the throttle body requires an adjustment in the MAF calibration.
Isn't this why you port the thing, for better performance.
I think you're better off leaving it alone, unless you're going to complete the project.

just my $.02
