Hi Guys,
Ok, I just installed an aftermarket GFB BOV (dumps to atmosphere and recirculates) Since doing so my boost gauge, which is stock now only peaks at around 5, before it peaked above +7. I thought i had found the fault just there as i found a hole in the vaccume pipe going to black box, so i cut it back and reconnected it but still the same issue. I cant seem to hear any boost leak(dont know if you would hear it with engine running)nor can i feel any leak anywhere? Is it possible the stock gauge is f**ked or is it more likely there is a leak somewhere along the line. Just seems funny as iv just noticed it after installing BOV. I was going to get boost gauge anyway so guess when i get that i can eliminate or determine if the gauge is at fault. May also try stock valve back on 2mo to see if the problem is still there? Any more help would be great and il update 2mo after trying stock valve back on.
Cheers
James
