Spooling with the parking brake?

[alexlaughlin]

Ever wonder why you can build more boost in high gears than in low gears? It is cause the trans is slipping.

Of course, but thats fine, let it slip to build your boost and leave hard to carry to the pan of the sled in the air as far as possible. I have a TC lock up switch I hit shortly after launch. So letting it slip is fine, just a little harder on equipment. Im still a little green in the pulling side but have some pretty good help. I'd rather pull with a standard but it's a Dmax and came with an Allison automatic...
