I've driven from Sedona to Phoenix twice this week, about a 2 hour trip each way. I've got the low speed set to 5 front/ 5 rear and the truck rides and drives great on the highway and around town. This is my default setting. Yesterday I pickup up 750 pounds of porcelain tile. This of course threw the handling and comfort of the truck way off.
So, first I tried 6/6. This was better, but by no means good. The trucks front end felt too light, like the suspension never had a chance to absorb bumps and irregularities. The front was too firm. The rear felt too heavy, bumps, potholes, dips in the road felt exaggerated, deliberate. Like I was using too much of the available travel.
After a few miles I pulled over at a gas station, and changed the settings to 5/7. The truck became a totally different animal. The front was well damped and firm, but completely soaked up bumps, irregularities, dips etc. Back normal. The rear was now responsive, quick to control the extra weight. It honestly felt like there wasn't a load in the rear anymore. The drive home was pleasant.
For a good reference to the AZ residents... If you have ever driven I-17 north, just after you climb black canyon up by sunset point, there are a few sections of road that are horrible in any car, or suv. Large dips in the road, especially in the right lane. Usually surrounded by skid marks. I hit that section at 75 mph with zero drama, no clenching or puckering. No bouncing, lurching, bottoming out or.. well anything. My wife pointed out the car in front of us bounced so bad it almost went off the road but the truck barely bounced at all.
I really like having the ability to change the tune as needed. The biggest thing is I have to teach myself how to use them properly, for there is very very little information about how to use your DSC's out there. I currently have the high speed compression adjusters wide open at their loosest setting. Every time I turn them up, the ride gets harsh. I suspect off road, I will prefer the low speed adjusters a 1 and the high speed turned up a little. Just need things to dry out around here.
