I'd definitely do it again, but it's not really fast enough to use for deflation because the outlet port for the air being released is absolutely tiny. That was a bit of a disappointment, but the valve that's part of the Air Up/Air Down tool from Innovative AT (https://innovativeatproducts.com/shop/ijkp-18-air-down-air-up-tool-with-gauge/) works fast enough that it's not that big of a loss. For inflation, I can air up all 4 37" tires from 10psi to 37psi in about 8 minutes. I didn't benchmark it against the dual compressor without the pressure control module in the path, but it seems plenty fast to me, especially since I don't have to babysit it.Can you please tell us your experience with the ARB Pressure Control system and the four tire inflation deflation system. Does it take longer? How long does it take to deflate? Are you happy with the system; would you do it again? I’m thinking about an AAL mount under my rear flap with the pressure control system. I also want to use a an air locker solenoid to tap into my airlift airbags to keep them properly inflated as well.
I ended up dumping pretty much the rest of the kit though, mostly because I could never get those push-to-connect fittings to stop leaking. I ended up re-plumbing everything inside the jeep with 3/8 air hose and replaced the external air hose connections with ARB quick connect chucks. I made my own hoses for each side out of 1/4" Flexzilla hose and fittings, and I'm a lot happier with it.
