OK well a gain of 16 Horsepower, however for the second run the humidity was a little lower also, so that may have a small effect. Raised the top power RPM too, so I think the biggest problem will be doing the back ones (not knowing what your engine bay looks like) but, i would say if you want the extra HP and dont mind throwing down the money...go for it. I'd want to see back to back dyno pulls so all the weather would be relatively the same and get a better idea for how much power truly was increased...
