but you buy those short ram kits for the response, not power gain imho. the time it takes for the throttle to respond is much shorter and a lot freer mid-band. stock box bogs worse when outside rev range. i use to be able to easily chirp 3rd but with stock box HPS+K&N = harder... actually havent been able to yet.
