I was looking at the Diablo and the superchip. They are only a few dollars difference in price. Any differences between them? Is there a general consensus on the best chip for fuel economy with occasional towing (or is this going to be like asking which is the best filter)? *ducks for cover

 

Yes, there are differences:

Superchips for 6.0:
Doesn't exist yet
No specifications released yet

Diablo for 6.0:
Exists now

Makes the choice pretty easy.
