Sport mode or 4 Hi for best full boost launch?

Thanks. One of these days I'll put the pedal all the way down. I haven't yet, lol. Just hit 10,000 kms in it this morning. So I might feel comfortable that it's sufficiently broken in now.

Mine is just under 22,000 kms..so maybe try it soon.

Sport mode will not make the truck any faster if it's already to the floor.... 4hi and spool it up

But 4wd will slow it down. More power loss.

Launch with rear locker engaged. It turns itslef off at 25 mph, so no added drag once off line

Can try it both ways. Thinking in 4 wheel drive, less chance of burning off the rear tires. Put my foot into one day, doing about 30 mph, and the back end broke free. Figure 4 wheel drive may help the truck hooking up.
