Marshall electric nitrous gauge not working?
So I bought a used electric nitrous gauge that is supposedly brand new, and appeared to never have been used. Well I hooked it up, and it was reading way high. So I go to crack a line from my bottle to bleed the pressure off and the bottle was luke warm to the touch. And wasnt completely full. Has about 6 or 7 pounds in a 10 pound tank. So right then I should have known the gauge was messed up. But anyway I bled the pressure off until it read around 1100. Made a spray pass on the dyno and only made 30 hp more on a 100 hp shot. So I guess what I want to know is if there is a way to calibrate this thing or do I have to buy a new gauge? Also can you just buy the gauge seoerately from the wiring harness?
