I would like to know how much of a gain in power are people getting from whatever performance chips they are using. How much gains are there to see on a stock setup versus gains inb a higher flow intake/exhaust setup. I would like to know because i plan on getting one in the future. I have a K&N panel filter, no intake or exhaust resonator, and a flowmaster 40s on single exhaust. I have a g3 vulcan. I'm guessing my current setup has gained maybe (hopefully) 3-5 HP. I know that a chip would take advantage of these modifications to gain power but what is the average amount of power gained?
