LS1 underdrive pulleys? 
any opinions as to underdrive pulleys; as in do you really pickup any HP gains or MPG gains as claimed by manufacturers and are any manufacturers better (more reliable or better gains) than others? i am considering purchasing the BBK pulley kit from LMperformance. appreciate any advice or info positive or negative. thanks, 2000 WS.6 T/A

From what I have read on here is that they really don't make a diffrence that you can feel, so it's really up to you if you wanna blow a couple hundred dollars on one.If it was me I would wait and save up for something else but that's just me do what you want.
