From everything I am seeing stock cars are showing around 270-275 and PPK cars around 295-300 on Mustang dynos. 20bhp increase seems underrated when it looks to be at least 25 at the wheels. Thinking about building up a car with the PPK tune, catted DP, PE, meth and intercooler. I'd like to see a solid, lag-free and repeatable 315whp.
Should make for a fun car that avoids any warranty issues on anything expensive. All the aftermarket stuff is pretty well isolated and likely won't affect other components. My dealer is pretty flexible anyway.
Step one is getting a baseline dyno next week. Then the PPK goes in but still debating going for the whole kit that includes upgraded cooling hardware since I live in a hot climate. Do the kits for 2011 sedan with sport pack use ducting that deletes the fog lights? I find conflicting information when I search. The BMW corporate site is vague on the issue. I really don't relish the idea of losing the foglights.
