I am having trouble with an 07 with the 427 asset. It will not build past 40 psi and it's slow to get to that. I also put a new reman compressor on last November but realize it could have an issue already. No air leaks at all. Interested in people thoughts thanks. Drier isn't bad bypassed it still the same issue.

Sounds like it could be air governor

Yup sound like the air governor

When you replaced the compressor you had to switch everything over, the compressor should also have a pop off valve, Have you checked it to make sure its working properly?

Soap, water, spray bottle. Start spraying.

Could be the check valves or unloader piston sticking.

try changing the 4 way protection valve this is most likely your problem looks some what like this down below
disconnect the little line going from the drier back to the compressor that turns the compressor on and off
try squirting a little CRC in the intake of the compressor while running
