Yes. There's noticeabley more pull especially in the mid-high end of the RPM's. I took it out for a short 5 mile jaunt and I can definitely tell a difference. I'll find out tomorrow when I'm on the highway, passing power should be improved.

For $250, it's worth it. I'm curious how it'll perform once I add the NeedsWings SCAI and 74mm throttle body, after they send me a new tune that is.
