6.4 vs 6.7 with same mods?

I know stock for stock the 6.7 makes more power. But I know the 6.4 takes to tuning very effectively. If both have the same simply mods; same intake, tuner and dpf delete exhaust which would come out with the most power? I know mine pulls like a train but haven't rode in a tuned 6.7. Also which would be faster? Don't need to get ride of my truck for a LONG time but don't mind doing homework for the future

Well you have 6.7s that sometimes might hit 13.9 in the quarter and you have 6.4s running 12.8-13.0 consistently so you make your judgment

Finally ran into one last weekend on the road tuned up with H&S.
Tell ya what, that 6.7 ran very well.. I was surprised.
He turned out behind me coming out of a parking lot around midnight, noticed his HID's.
Before I even looked again he was to the floor and attempting to come around me so I hammered it.
By the time I got on it he was already next to me, and began to pull on me. I was probably doing 35 or so when I put it the floor.
By the time I really got going his front end had just started pulling ahead..
Took me a quick second but I gained that quickly and began to pull instantly in overdrive too. He let off as soon as I started waving and pulling ahead.. Right around 70mph.
I don't think he would of even got ahead if my trans could ever make its mind up.
Still his truck ran very well and from a stop I definitely think we would have them.
Just thought I'd share and my experience.

A 6.4 will smoke a 6.7 in modded form. Stock is another story, the 6.7 is quicker stock.
