hey how you doing buddy...

 

I've done it during wet conditions to get a kick *** launch!

 

u will b fine.. i do it all the time when i go to the track.. its just so i wont spin out the hole then back to 2wd... and yes if ur tuned defanetly put it in tow/haul mode... ur not going to hurt anything.

 

I thought that was the whole idea of a 4x4 on the track? launch in 4Hi then switch back into 2 if you can.

My tune is set up 0% TM on tow/haul so it helps to push that button too.

 

Essentially all depends on how your tune was set-up.

...I'm pretty pissed, I'm having issues with my 4WD actuator, it'll reject switching to 4hi when the truck is at operating temps, but will switch back and forth just fine when cold starting...
