I have no way of knowing if this gauge is accurate. And I never tested my pressure when the truck was running great which was right up until after I hauled a car halfway across the country last august. It was then I started getting lean codes and it does this bucking thing when Im in overdrive like someone is tapping the brakes every half secondAre you confident the gauge you are using is accurate? Don't assume that just because a part is new that it was correctly manufactured or correctly labeled.Did you inspect/replace the tiny bit of vacuum hose that runs the regulator?
