I have the coding software but haven't used it for years. Never needed to use it. I think of it as going to the dentist for a root canal.

I had the front up in the air for about 2 weeks. When I lowered it one of the rear airbags didn't inflate. After 121,000 miles this is the first airbag to go out. Vehicle has been sitting for several months. I started it frequently. Last time I started it both sides were deflated.

Haven't verified the compressor is bad yet but I suspect it has died also and would rebuild or replace it when doing the rear air suspension anyway. So I am looking at the cost of air suspension rebuild as a deduct on the price of coilovers. I already have the H@R lowering kit but I would like to go lower.

Suspension is modified already and high speed handling is better than I need for the street. I am assuming coilovers will add to handling at highway speeds.
