It is a 5 minute install, 3 -7mm screws in the footwell where a foot operated e-brake would be, 2 quick disconnect plugs that are color coded. Prior to install I saved a copy of the baseline config maps. You certainly don't have to, it is plug and play, but I'm the type that will analyze and play with the settings. The plug adapter is conveniently located for very easy connection when I do change maps, about 5 seconds to open drivers door and plug in. My truck is a SCAB, with Deaver +3 out back and 1.75 collars on the front. I took a test drive around the block with several speedbumps and turns. I could tell a difference in seconds; much softer when no G loading, and instantly / progressively firm and predictable when any G s from turning or braking. It swallowed the speedbumps much smoother in sport mode than the stock unit did in normal. I'll run around for a few weeks with the factory DSC settings before playing with the tuning tables. Plan to be in the desert or mountains during the Thanksgiving holiday. I do off-road the truck, but for those looking for feedback on high speed runs down the rutted trails, that's not me, I have a buggy and bikes for that. I have the DSC sport for a C7Z06, so am very familiar with how tuneable this is. For me, the extreme tuneability of the DSC ( easy with lots of online tutorials on the DSC site) outweighs the dial a tune of the e-click. Also, big kudos to Tom at DSC, he answered my detailed calibration mapping questions within a couple hours of me sending an e-mail...the info is not something needed to use the DSC with factory maps, but I'm eventually going to play with the maps and wanted all the details.
