Hey, if anyone can kinda help me answer a few questions and point me in the right direction, id really appreciate it. I've finally bought a bagged 99 tahoe and in all so far, everything seems ok... When i seem to either raise or drop the truck, it always seems that the front passenger bag is deflating faster, and inflating up slower. Is there something that would adjust the speed of inflation and such? Also, its got a belt driven compressor under the hood. Seems to work great, but im not familiar with them. Anything to watch out for, or to regularly maitain with that type of compressor? Or with any bagged vehicle what is the typical regular maintnence? If you have any advice for someone new to this id really appreciate everything. Thanks  

you can get flow control valves that will help it raise and lower level.

Be sure to keep the tank drained water will build up fast in them.

Valves will need to be cleaned periodically....Google "how to clean (insert valve brand here)" for a how-to guide
