To use the analogy of the smaller motorcycle vs a bike like the gsxr1000. Imagine that you are competing in a superbike race for the first time, and your team gives you a moderate performance type bike, not really a bike that you would race. You go out during practice and just wring that thing out. You find that bikes edge and ride on it. You feel like the greatest rider ever. Now, time for the race, and they bring you Mat Mladin's GSXR 1000! You have never been on a bike like that 200+ horsepower, indeed a scary ride. The first time you come out of a corner and lay into the power of that thing, and the rear end comes out from under you, and you high center. Sound like fun?
May be a little long of an analogy, but you get the idea.

Run the c6, and then rebuild it as needed.

I have a c6 BBT L2g in my 8b by the way, and love it.
