Is that on a Mustang or what? Seem low across the board to me. Almost 22% stock driveline loss? I've seen people claiming 400 rwhp w/ plenum, TB, tune, and race headers.

Great pick up. You will love the car. If you want to hear it sing, get a set of race headers and open the valves on the muffler when you drive. It sounds fantastic. I have a Soul race headers and the car just sings great porsche music. Its so fun driving it. Even the wife somewhat likes it. haha.
