I'm wanting to fit a boost gauge to my 3.0d but need some advice on the different types.
I have attached pictures of 2 that I'm looking at. One starts at 0 and goes up to 3 bar, the other has what I assume is vacuum to 0.8 and maxes out at 2 bar.
Which should I get?
Do I need/can I read vacuum? Also, where is the best place to attached the T piece? How much pressure does the 3.0d even make?
