Your gauge setup looks great and you can definitely tell that you put in some time. You mentioned the Defi HUD unit... are those Defi gauges?
These are Defi Racer gauges, requiring wires for 12V switched, 12V constant, ground, and illumination for each gauge; but do not forget about each set of electrical wires that follow in from each sensor sending unit. Had to grind out a suitable hole though 2 layers of firewall metal and plug it with a body plug holed in the center for pass-thru of the looms. That was music to my ears while the rotary bit was hitting stall speed and notes I hate to hear when metal is gauling.
Defi has better gauges that use a single wire for power and all the communication to each unit, but they also require a main control box. Hud was use the control box as well, and require some sort of speed sensor tapping.
Issue:
Gauges like boost are sometimes hovering in a weird range other than the 10-15 inches my engine showed with the old Autogage Carbon fibre 30-0-30 unit. I was sitting in boost before it settled down later, and this was at idle. Other gauges like the Volt meter were in the wrong range for what my logger used to show at the ECU - too sensitive?
I have all the switched power wires bundled, constant power wires bundled, and ground and illumination bundled all into respective single connectors to run to each feed appropriately, and was wondering if this would have any effect on the performance issues I'm having. At least the coolant temp is spot on, and I have yet to test EGT until I get a bung for the exhaust.
