imo = in my opinion
An Underdrive pulley (UDP's) will reduce the amount of loss in the driveline; it does not CREATE power. The gain is really that reduction in loss. And UDP's MAY give you about 5 RWHP. If the 10-14 that you state is advertising, you need to take 2 "no-longer-gullible" pills and call me in the morning.
If you want to gain power, check out the Cold Air Intakes (CAI's) and custom tune combos on Brenspeeds and American Muscles websites.
