I did install my MPT tune (93x) Saturday and so far I have been very happy with it (although very limited driving time). The increase in power is very noticeable especially when I push the truck. I get more of the "snap your head back" feel than I did before when pushed in the Raptor. I am very happy that the normal driving dynamic has not changed that much, ie the throttle is not twitchy and the shifts in normal seem very smooth. Overall Normal mode feels just like before, just with more power available when I ask for it, which is exactly what I wanted. Sport mode really opens up the truck much more than before, but I only drove in Sport for about 10 mins so far so i don't want to judge it too much yet.
I'll drive a lot more this week including about an eight hour road trip on Thursday and I will come back and give more thoughts on it then. So far the results have been excellent.
