Boost gauge installed

Thanks to some posts on lighting connections, TDR articles, and good instructions, the install went without a hitch. That engine and hood sure is tall though. The gauge works fine. It screams to 30psi and then drops back to 25, is that the waist gate opening to limit the pressure to 30psi? If I don't floor it it will get up to 25 or so and stay with just a small dip when it shifts. Thanks for all the posts that made it easy!

Mine is stock and the highest pressures I see are around 31lbs and then it drops. Don't stop with the boost gauge. install an egt, FP, and a transmission temp gauge if you are going to tow...

Right now the heaviest trailer I have is a car hauler with a Jeep on it. Only about 5500 pounds plus or minus. The boat and my utility trailer don't even make it break a sweat. I think I'm good for now. I think the waste gate is opening to lilit the pressure. If I sneak up on it I can reach an maintain 30 if it goes any higher it jumps back to 25 and jiggles around a bit from 25-28 or so. I do love this truck though.
