I mean, I re-programmed the computer and later took her out for a test drive and it was ok, but to be honest I really didn't feel that much increase in power. Off the line it accelerates alot better and seems to have a little more throughout the rpm range, but they were telling me I'd definately feel the power and said I would gain around 20hp. Anyone else here experience this??? I mean, I'm not saying I'm not happy with it, but really, I was expecting a little more seat of the pants gain.</p></blockquote><p></p>
