Do any manufacturers have a tuner for my new 2020 Yukon Denali 6.2? Primarily I want to delete the V 4 AFM.

Why delete it?
Unfortunately we are not able to tune the 2020 vehicles. We use EFI Live for tuning. Also on a side note, we would not recommend disabling the AFM, or DFM, on the 14 and newer vehicles, it is typically a fuel save now, so we would only suggest disabling it if you have heavy wheels/tires or can't tolerate the sound with your exhaust.

Do the 2020 vehicles have the new style computer I've been hearing rumblings about due to being fully locked out by GM? if so, I'm hoping someone can hack it...
Yeah, unfortunately they keep tightening the security since the 2017 vehicles, locking the 8 speed 10 speed transmission controllers, some 2019 vehicle we still can't tune, and no 2020. vehicles.

The AFM can cause problems. A friend of mine has cylinder 7 causing problems on a 2015 5.3 and they are doing a tear down. Going 8 to 4 to 8 all the time can have its problems. Blackbear solves this along with more hp/torque, TCM mod, tip in acceleration fix. you name it. No brainer.

Hmm. I've been running your tune along with AFM delete for months now and it's great. Why would you recommend against the AFM delete you provided me?

In fairness mine is a 2015.5 with the 8 speed and 6.2. It could be as simple as breaking code.
