As spiked jack said, I also use my boost controller.
Safer to have the restrictor ring at something 1.1 bar and use the boost controller to get to 1.2
Greedy Profec B 2 is what I have.
As far as other Gauges go I have an AFR coming and will be adding EGT, water temp, oil temp and oil pressure.
Just need to work out where the EGT will go as want to keep my vents.
AFR in place of the clock, with oil and water under the stereo.
Have seen pictures of a gauge below the ciggy lighter before, so that may be where the EGT goes.
Was looking at a screen to do all but will probably have to go with budget gauges for now.
