I've got Eibach 2.8" lowering springs and DJM Suspension track bar brackets, shock extenders, and shorter anti-sway bar dogbones. It pretty much leveled the truck out. I ran with only the lowering springs for a couple of years and didn't like the ride and drive so I added the DJM Suspension parts. It made all the difference in the world and the ride returned pretty much to stock. The spring rate is a little higher...

Ok, I tried all the steps I used above, plus hooked up a charger to the battery.  I am still getting the script error.  The only other aftermarket add-on that I hadn’t unhooked yet was the CB, so I pulled the fuses from that.  Still didn’t work.      I tried several times, and I did get a couple new errors; access denied, and wrong key or something like that.  The more I try,...

Every GM forum is asking the same thing. I hope they make one for the 2002 Avalanche.

i love my edge, yeah, pretty much just makes it go faster, not much for fuel efficiency.
