    fpr vac line is a popular option. i deleted all gubbins from my bay so had a spare vac port on the inlet mani so used that.

    For me I like the idea of the FPR having its own dedicated vac line.

    As above though, I used a spare vac port from under the inlet mani because I removed all the **** that wasn't required.

    N249 bypass is just bypassing the N249 with a single 4mm ID length of hose from the inlet manifold to the DV. If you want a boost gauge then T into this new length of hose
