Hey guys well I just got my gryphon for my 7.3 powerstroke. I have installed it and just been reading the gauges on stock tune. Anyways I wanted to know how accurate the boost gauge is? I floored my truck and most boost I got was 10psi. If not mistaken it should be twice that amount. Any idea on what the problem could be. also I tryed the canned 60tow tune and does not seem any faster than stock and still showing 10lbs as well.
