Issues with my airlift autopilot v2

[bknewtype]

airlift autopilot v2
2 compressors
3/8 lines
4 gallon tank

this is a long shot, as I know issues is hard to diagnose without having someone check the system physically, but I thought Id get some ideas here if anyone has any

during the winter time last year int he BRUTAL cold ( talking about 20 degrees with a real feel of -10 ), while driving I heard a pop noise in the trunk ( that's where my setup is ). went to check it and everything seemed fine

as days/weeks/months goes by, I noticed that my rise to start was not working as it used to. I usually air out while I park, and once I start the car, it automatically lifts to 100 psi. right now, it just sits there for a few minutes before it goes up. I check the remote, and its because I start up at around 20psi in the tank, when it used to start at around 100. so I believe I have a slow leak somewhere. now I have to sit and wait for the tank to fill up anywhere near 125 before I can air up to 100psi and start moving ( my garage requires it ). I have already checked all the hoses with a spray bottle/soapy water and all the lines look good. I did the balloon test with both compressors and the water traps under my car, and no air leaking there.

anyone have any idea where else I can check before bringing it in? visually there is no problems and all lines are 100% intact.

and yes I know I can just not air out before I park so I can start up and move, but I just want to get it back the way it was

thanks in advance

I'll see if my buddy can answer. He's our local Airlift guru.

Appreciate it! I know its hard to diagnosis without seeing everything , but my buddy who installed my air did a visual and hose check everywhere and no issues :(

Really hope i don't have to take it apart to find the issue

Could it be a leaky check valve?

I sent him the link. Now if he'll answer is a whole other thing lol. You would be amazed at the hack jobs he's seen, so I figure he'd be able to take the best guess...
