bumping compression that much makes a huge difference, plus with digital ignition you can add or remove timing which again helps a ton. standard 0-200 exhaust is terrible. power pulses are constantly fighting back against the next pulse of exhaust exiting the adjoining cyl. There is no need to spin it fast as the power increase comes from the increase of downforce from the higher compression/timing/free flowing exhaust. A 20 hp increase is easy to attain by just increasing efficiency. Remember, the mods have to compliment themselves, smoother more free air coming in, more compression to utilize said air, and a better way out.
