I had a bad experience with an Airlift controller on my previous '02 and I swore a better install this time around. It was an auto controller and the pressure sensors went bad and I couldn't get replacements. It was almost uncontrollable at best. I ended up putting a power switch on it and then manually controlling the bags and then turning it off so the automatic operation didn't take over.
This time I started with a manual setup and Firestone bags. When it is done, I will have tank and bag pressure readings on the CTS and electric solenoids for the independent bag fill and dump. I currently have the dual gauge and pneumatic valves in place below the cup holders until I can get some time to dedicate some energy to completing the install.
