Are there any custom files/tunes available afterwards? Let's say I decide to install a DP, cat back and IC in the future, I'll need a new tune for sure!

I don't think that's how it works with Ford racing - pretty sure they don't offer tuning services. Now ... if they come out with another kit that requires a different tune, they would undoubtedly include it.

Having said that - I doubt that the mods you mentioned would absolutely require a new tune.

For example - if you compare the specs for the M-14204-FST (calibration tool + plugs) vs. the M-9603A-FST (calibration tool, plugs, filter, CAI) vs. the M-FR1-FST (calibration tool, plugs, filter, CAI, cat-back exhaust) ... they all show the exact same increase in power. In fact, on the Ford Racing website the dyno sheet they show for all 3 part numbers is the one for M-9603A.

To me, that's the kit you want - because it seems pretty clear that the power comes from the new tune and not the bolt ons - which makes sense to me with a factory-boosted car.

Last year's dyno day was a pretty good demonstration of that. Of the three STs that pulled, the torque numbers were all pretty much within spitting distance of each other despite some real differences in the hardware. It was the kind of difference you might expect from one car to the next. The one thing they had in common was a new calibration.
