It’s wont meet the desired max psi in any tune is what I was trying to say, LJC is the tuner and he’s always been great. I don’t always run the EXTREME tune or MAX tune and I’m usually in the lowest TOW tune on my MM3. This morning I returned the truck to the stock program since I had to run inside the grocery store and driving it home I tried to see what it was doing in the stock tuning and it still only maxed at 26233 psi going off the MM3. So I got home shut the truck off and disconnected the FCA and started it up for a couple seconds, and the rail pressure was steady at 29645psi. I’m starting to wonder if my lift pump pressure to the CP3 is what’s causing the issue. Anybody have a easy way to test the pressure? I’m a mechanic and have some gauges and fittings LOL. Surely with the CP3 bag of parts kit and stock tuning I should be able to see more rail pressure?
