i bought a f1a fmic setup from EPP almost a year ago and now getting ready to put it in. i just realized that they sent me a 10% underdrive pulley instead of a regular size. i also asked them to give me a pulley so that i could run 15lbs boost. im now worried that my boost will be thrown off bc of the underdrive pulley.

so my question is will this effect my boost level?

Yes, the underdrive pulley (pn# 917276) is only for the accessories. The ProCharger pulley bolts to the outside of it. Now get the blower installed! lol Bob
