3/16 vacume mod - what in the world is this?? I have read a ton of forums and signatures on this club, but I am still confused as to what this is. Does it help something??:confused:

if my browser would let me on i-club right now, i'd get you the link, but just go to www.i-club.com and search 3/16ths mod.

it supposedly allows the wastegate to stay closed longer. i noticed my boost gauge coming out of vacuum faster.
