I just discovered this Spoolinup COP today and am wondering if people have any first hand reviews from before and after. To me it sounds like a lot of hogwash: higher HP and better MPG. To me that's a contradiction. But if it's true, I'm all for it. I'd get it for the smoother ride. I don't like that partial throttle bumpiness that I get sometimes and this is supposed to reduce/eliminate that. Thank you in advance for whatever input you may be able to provide!!!

 

Nevermind, I finally found a 2 year old thread
