I don't think you could ever argue that the MS will always be better than a AIC unit like the PF, expecially with all the progress going on with the MS, You can change the code it runs on, control everything under the sun, and do it all a lot cheaper.

The only advantage the PF has over the MS, to my knowledge, is just simplicity. Set it, forget it, use your OEM stuff unless your in boost, easy to install, don't have to wrap your head around a 'stand-alone type of solution'.

In the end, I am sure you would be able to squeeze more power out of the MS than an AIC, or I would sure hope so with all that extra tuning ability. So if that is your desire, to be the fastest.... Looks like that is the route to follow.
