My new to me 2018 Yukon Denali Ultimate

[MrMonte]

2 months ago I purchased a low mileage 2018 Yukon Denali Ultimate. Since then I have put 5,700 miles on it with an overall average of 20.5mpg. 125 miles ago I installed a 91 performance tune and turned off AFM using a Flashpaq F5. So far my mileage is at 22.3.

Near plan is to do a full detail then coat with Cquarts 3.0 ceramic coating.

I used to have a 2007 Escalade. I also have a 2000 Suburban 2500. My son has a 2015 Yukon Denali.

How do you like those Hellwig sway bars? That's on my want list. The factory tires have terrible wet traction so I should be rolling on some 305 Michelin Defender LTX M/S tires by winter.

The Hellwig sway bars are nothing like anything that you've ever experienced. They virtually eliminate any body roll on the truck. Both myself and @OR VietVet installed these sway bars, and we gained significantly improved handling and speed on our test cloverleafs, without significant body roll. Tracking my Z55 suspension in real time with my Tech 2, the Hellwig sway bars have taken at least 50% of the load off my electronic suspension for truck stability. They are pricey, but well worth it.

The Michelin Defender tires handle excellently on anything that the NH winters can throw at them. They are quiet and expected to last for 70k miles. Again, they are pricey, but well worth it.
