2019 Chevy Silverado 5.3L with DFM 8 speed (8L90)
Seems to work. Disables auto start stop too. Tested it on a 2019 Silverado with DFM and a 2020 Tahoe with AFM. Itâs easier to tell on the older gen Tahoe with AFM because it shows you if youâre in V4 or V8 mode. The Tahoe always stayed in V8 mode. When using it in my 2019 with DFM appears that it doesnât work until you go over 40mph because the instant MPG goes to 99mpgâs when you coast but stops doing that after youâve gone over 40. However the instant MGPâs do the same thing in the AFM Tahoe which shows it always in v8 mode. Not sure why it does that. Still gets 5 stars.

Seems to work???
No instructions came in the box. It switches from 2 lights to 4 lights but I have no idea if this means itâs working. Some explanation for the light would have been nice.

This works great
If your ready for it to run on all 8 cylinders, than be ready for it to burn through more gas â½ï¸

Noticed a difference in acceleration and smother trans shifting. Haven’t noticed much difference in gas mileage. Would recommend.
