Boost Gage on Quad Commander
I have a 2004 6.o Excursion. I recently installed the Quadzilla Commander for the gauges only. I do not have a tuner/programmer/power module. The boost gauge has been reading low, 15-18 psi under full throttle acceleration. I took the truck into my local dealer, who I trust and has always treated me very well, and they drove it with their computer hooked up and read 26 psi while the commander was reading 16 psi.
Did I install it wrong, is the commander in a wrong mode, or is there a problem with my commander? I think a tapped into the correct wire on the MAP sensor.
