Diesel truck lovers and Hoonigan fans, here's the episode of Dyno Everything you've been waiting for. It doesn't feature a fire-breathing engine boosted to the stratosphere, nor is it rolling with a ginormous suspension lift. What we have here is a good ol' GMC Sierra with some wheels, an engine tune, and according to the truck's owner, that's it.
To be specific, the truck in question is a 2020 GMC Sierra HD Denali packing the turbocharged 6.6-liter Duramax diesel V8 engine. Intercooler piping is upgraded, and it's running a tune that goes to "stage five" per the owner, though parameters on the tune aren't mentioned. Underneath, the suspension has a leveling kit with Fox shocks, and it all rides on Fuel wheels.
