air bag it problems

[fredscarryall]

i bought an air management plug and play system from airbagit.com.when my suburban has air in the system in about 10 minutes one side drops to the running board. the autoloc controller wont tell me how much air my tanks have and my remote control key fob is suppost to have 4 presets but it wont work. i sprayed foam soap on all the lines and i have no leaks and i have done all the programing from the instructions. i contacted airbagit and the customer service has no clue.i cant return the system because once you install it the warranaty is void. they dont have a tech dept.they just make the parts and put them in a kit. does anyone know a trick to getting these kit to work right or can give me a information on who to contact that know alot about these systems.
