I have recently fitted a Chip-It chip to my ML along with a EGT monitor. So I can keep an eye on the boost I am also want to fit a boost gauge. I have decided to use an electrical gauge, but struggling to find a suitable place to tap into the system to place the boost hose.
I have seen a few posts of other members showing that it can be done and would really like a bit of guidance on where others have tapped in.
