would a 2.5 in ic pipe make a difference? or is that what the stock rubber size hose is. someone else told me that it goes down a little because it has a little larger diameter pipe, sounds like bs to me. but i am goign to boost leak test it soon. im in the middle of making a boost leak tester.

 

You will loose PSI but not much. I mean a FMIC you usually loose like 2 psi so pipeing shouldnt really make much noticeable difference.

I say if you have a leak it is coming from either the BOV or the pipe and couplers that you put on (the new stuff)

 

i agree

 

ok cool. well how do u plug off the mbc?.
