That’s right and why I want them under load all the time, guess I’ll just keep the rev’s up and manual shift

Ordered 21 RST 6.2, Z71 GM exhaust, intake, 2” lift an a power up tailgate. The DFM I don’t like the idea of cylinders cutting off, will tow mode or sport mode keep them from Activating? and is it ok to stay in these modes forever. Heard 10sp has 3 od gears what shift point keeps the DFM from kicking in, not concerned about gas or mileage. Coming from 5.3 Alpha Hummer AWD. only concerned about all lifters an ****** getting oil
