Special thanks to the DSC Sport team for my newly acquired controller (on the truck above). The team is amazing and they really know performance racing. That was exactly what I was looking for. I showed up, asked a bunch of questions, they answered every one and installed my controller + zeroed.
Summary: The controller is simply amazing! I noticed the better handling immediately (literally as I was pulling away from their shop in the rain). This was exactly what I wanted in driving behavior with the live valve technology. it almost feels like it was designed/tuned for the track.
Context: I have a pretty stock 19' Raptor daily with the exception of the VenomRex 17 wheels (special thanks to nick@apollo-optics) and the Ford Performance by Borla exhaust cat back. My goal was to achieve better handling in urban environments and off-roading while keeping the truck as close to stock as possible. i live in a urban area and use the truck to drive /transport parts to various military installations. I'll be honest, I drive my Raptor in urban areas pretending it is almost like the Baja 1000--mostly b/c the potholes and other landmarks/drivers demand aggressive driving--especially where I live
. I don't plan to do much towing or overlanding b/c i have another rig for that. I just wanted a fun truck for street and occasional off-roading. And, i didn't want to mess with the geometry much e.g. suspension,springs,leafs,etc.
Analysis: top noticeable characteristics with the controller-- 1. cornering (wow, is it fun not to wobble all over. it almost feels like enhanced damping), 2. braking (the nose is not all over the place like before. my son thought I switched the front springs out when I gave him a test drive) 3. pothole absorption (much more controlled; just soaks them up--especially in the rear), 4. towing (more controlled in lightweight towing, but i didn't need to switch to a towing mode. all modes are much more controlled, but tbh, I found 'normal' to be surprisingly sufficient in aggressive cornering in wet/slippery terrain, braking, object avoidance and towing. Lastly, 5. less rear-end hopping..the absorption was noticeable--felt much more controlled at higher speeds.
I haven't tested off-road yet (although many streets in the city should be considered off road), but I will report my findings once achieved.
In short: my opinion: this controller is a must have if you want better performance without messing with springs/leaf. I found the value more noticeable with more aggressive driving. at low speeds not too much difference, braking benefits are much more noticeable, but the controller really shines with aggressive driving, imo. I'm sure it will be fine for springs and leaf upgrades. If you're looking to keep the Gen 2 19/20 stock, but want better handling, I think the controller is worth the investment.
I will certainly return to DSC Sport for future upgrades.
