Any turbo approaching 30psi/~2bar (3bar asbolute) you will want to go up to 4bar MAP as the 3bar won't show spikes above 3bar absolute. I switched to 4bar when running 1752vrk turbo (2.0-2.1bar) and now 2260vklr is around 2.4.
Tap into the MAP hose, the hard plastic piping can crack and also has a lot of turbulence in the pipe that resonates to the gauge even with those little in-line "buzz" connectors. My autometer gauge tapped into the MAP hose and one in-line buzz connector is perfectly silent!
