Gze Abv Mod

[TruenoGTV]

I fitted the Fensport 175mm pulley but still getting 8psi boost, when I should be getting 12-13 psi. I have already done the abv mod. I am thinking of removing the ABV as I have heard that they can be a bit sticky.

Has anyone got any ideas how to block of the ABV?

Check you dont have dodgy gauge.

Youll laugh but I was nearly defeatedby a cheap boost gauge that stuck at max 8 psi. Check for belt slip also.

Are you sure you did the mod right?

Inlet manifold to T-piece. T-piece branch to ABV, other branch to brown VSV, brown vsv to FPR. Block the blue VSV off or loop it back on itself with another T piece.

Pics??
