It won't run as well at a track and it won't run as well in crappy traction, but it won't hurt anything. IIRC the center diff has some mechanical locking in the 07, like 10% or something like that, even at wide open. It'll do some sweet burnouts too! Spiider has a model where you can turn off the DCCD for a reason. Keep on reading buddy.
So can you put it on the dyno w/o the DCCD controller? Seems weird that my shop would say it's not optional (they've done quite a few swaps).
