2010 sierra with 6L80. How do we make a custom/separate tune for the t/h button?

the trans settings can be adjusted for tow/haul in the tuner, engine tune is the same either way

so whatever changes are made in the TCM settings will be the same for tow haul mode or regular mode?

no..

there are separate settings you can change/adjust for tow/haul mode and normal/regular mode...

How do you make the fans come on sooner in the tow haul mode?

you can't.. fan settings are for all modes..

the tow/haul mode just tells the tranny to use different shifting settings, that's all it does.. the engine tune does not change.. the engine tune is always the same for all modes no matter what..
