I did a wot run on my 120max tune to check my rail pressure. I had my 28' gooseneck on back. The rail held 26k np upto 70. Then I came to a stop sign and my gauge read 0 on rail pressure. But once I hit the pedal it'll go up as I accelerated. Then I came to a stop and 0 again.. So I turned the truck off and let the airdog run for a few then started it. The rail held 5k.
so this morning started it and got things warm and did another wot run and came to a stop, got 0 again... My gauge is working so I dunno little stumped.. It jumps off 0-100 as truck idles.. No leaks or pools of fuel
