Intersection points are different on the pulls. The one crosses at 5250 like it should the other at 5500 or so. The overlay isn't even or the scaling for hp and torque are different I'm not sure.
Lol
The choice between PP2 and PP3 comes down to what you want to gain. PP3 will open up the high end with a less restrictive IM. PP2 retains the flow restriction of the stock IM while supplying denser air.
I'd say if you have 3.73s, you should strongly consider PP3. For 3.31 owners, PP2 makes more sense. No one wants to go 75 in second gear, lol. There will be losses under the curve, and you spend too much time in that range with 3.31s.
For my application, very little time is spent at or above 5,000 RPM. Any top end gains are a waste. A 13% boost in torque on the bottom end, though, would get used almost constantly!

Thanks, just saw it on Ford's site. But for over $2000, the gains don't seem very noticeable on the lower RPMs (city driving, below 4K RPM). And that's where Mustang suffers on low RPM TQ.
