Greddy Profec B spec

[vboyq]

i remember a dyno test where they tested all the different boost controllers...any ways i believe the b-spec 1 won. is the b-spec 1 better than the b-spec2? also wat makes the b spec better than the more expensive boost controllers?

its really simple and effective thats why. it also has a feature to where you can control when you want the wg to open, for quicker spool. i have one and love it.
