    I only tapped in to the vac pipe going to DV. I will be fitting a boost gauge soon (not the 1 i uploaded), should i plumb into the vac pipe coming off intake manifold ?

    Yes... assuming you still have the N249 connected up then I believe the vacuum could be different due to the vacuum store....
