Alright so I was looking at underdrive pulleys for my '04 and it seemed like BBK had a good selection on the 3 piece underdrive pulley kit. Does anyone know anything about them, have them on their truck, or know if they even help? Good and bad reviews? I could go searching for hours on google about them but why not do it on here, my F150 brothers alike haha. I was looking at them mainly to help with a few hp but also because they look good on the motor. All input is greatly appreciated and if you have them where did you buy them from at a good price?

I installed the ASP underdrive pulleys on my truck about a month ago. Im getting ready to do a little write up on them here soon. I just want a little more time to gauge my Fuel economy to see what i gained. This is purely my opinions as i have not had my truck dyno'd yet...waiting on my programmer to arrive. Just so you know you will not "Gain" HP but you will free up some that is being lost to parasitic drag. You will free up 8-10 HP with no custom tune for your truck. With a custom tune it can be between 10-14HP. You will also get about 1 extra MPG out of them. YOu will notice a little more "go" all the way through the powerband. I think your best bet for mods go like this...Exhaust, Pulleys, Efan, Custom Tunes with a Intake. Hope that help's, let me know if you have any more questions.
