Just updating this post. I have had a chance to drive the car a bit since the install and the engine definitely feels more responsive. This is just based on the butt dyno so take it fwiw. If you have the means I certainly recommend this mod. And I must say I very much enjoyed the install even though it was a major PIA getting the belt to fit.
