I have a question i installed i t 2 days ago , i dont really feel any diff. Boost still feels the same. The question what spring did you guys run when stock or recomend for stock. Im running the green with no washers. The yellow and blue came with it. should i addd any washers or swithc the spring. I just want to see what spring and washer if any you running with your setup. Thanks

 

I ran the 15psi spring just cause the green with washers felt almost exactly like the Old Bosch that came with the SC. I was also running the ZPI SC pulley

 

you ran that spring after the install on the pulley. How many washers did you run. Also they go at the bottom , correct

 

anybody else have it, lots of views, i know some one else has this bpv

 

My friend runs the blue spring with no washers.

 

what are his mods
