My FIST just arrived yesterday and I am picking up today. I already have the MP 215 kit in my garage waiting to get installed by the dealer. I am actually happy that the torque limiting is still present with the MP 215 as spinning the wheels in the lower gears seems pointless and would affect low speed handlingFWIW, I had the MP215 installed today. I was a walk-in customer to my Ford dealer and they got it installed in 45 minutes, no problem.
There is a noticeable increase in power, mostly in the mid range torque. The car pulls hard all the way to redline now. I thought I'd be annoyed at having the kit keep the torque limiter, but honestly it's not a concern to me (1st gear simply spins tires now...not sure how increasing boost would help?).
I'm a happy customer and would recommend it to anyone in a flash. The only concern I have is that I'm only getting 21psi of boost WOT in third.. I've seen reports of people hitting 23psi. I'm wondering if I have a loose hose clamp somewhere?
