so i should go with the 10% rather than the 25% underdrive???? im getting the powerbond one and thats the only percents they sell, so what does the 25% and 10% mean exactly????

Don't do an underdrive pulley, bottom line. The poor affects of the pulley are not worth the 5, maybe 10hp you'll gain. Put the money towards something that won't kill your charging system and battery, overheat your car, weaken your A/C system, and God knows what else. GM made the pullies the size they are for a reason.
I agree. Nickels and dimes worth of HP arent worth the hundreds you'll pay for it. You could pick up a used cam that would throw 40RWHP your way for that kind of money. If it were a $50 mod then yeah, its worth it.
I certainly didnt feel the 11hp the TB airfoil was suppost to add for my ol' LT1, nor did i with the pulleys. Now as I recall you could feel the headers and 4.10 gears, lol. For $200 theres a better performance part that you'll feel.
