I have a 2018 with a 4 inch Fabtech lift. I did elect to go with Deaver 4+ rear springs to eliminate any block in the back and the potential axle wrap. While doing so I had the Wimple Stage II kit installed along with a custom tune and Borla exhaust.. It is putting out 600 HP and I like the fact when I tow my boat that the rear doesn't sag. With the work by Karl Krohn at API racing here in Salt Lake City, this thing now flies. No loss of ride or off-road ability as far as I can tell and that is after having the Raptors course here in Utah and well as two trips to Moab. Perhaps things change, but after 6 months of lighting it up I have had zero problems.
Did the installer give you Dyno numbers to back up the claim of "putting out 600 HP"? If not, you should ask for a refund because there are no tunes and/or IC/CAI/exhaust mods that can get you to 600 HP on our trucks. If they upgraded your turbos and did a whole lot of engine mods, you "might" get there, but your reliability goes way down...
