Thanks Stone. Always helpful.

That's a lot of $ for only 10hp. I suppose it's only a piece before you get to any real gain.

There are a lot of threads about programming, throttle body and intake plenum and exhaust changes and how much HP they add to an otherwise internally stock engine. Some of those gains are in peak HP only at peak rpm and the power, torque and driveability suffer everywhere else below that peak, meaning you may never feel any gains on the street. I believe that was Jake Raby's experience when he used to post here. After reading a lot of those posts, I decided to just have an underdrive pulley installed and leave everything else stock. YMMV!

Thanks Paul. Did you notice a difference on the street?
