Re: H&S first with a real tuned 6.7??
Well if we remember back about 1.5 years ago, there was quite a bit of argument about whether or not there was much more potential for the 6.4 beyond the 520 hp mark. The 6.4 tuning didn't reach it's peak overnight or even within the first year.
I think we all know that this motor will likely do great things, but the only thing we can do for now is play the waiting game to see how well she stands up to the added power.
