WHY CAN'T WE GET THE SAME OUT OF OUR 6.7

Coming from a 6.4 it is a little disappointing that we can't get the HP out of our 6.7 that is available for the 6.4. The DPF off tuning available for the 6.7 is not much more than the DPF on tuning for the 6.4. Does really come down to the difference in the turbo? I look at the H&S website and compare the 6.4 and the 6.7 and it is amazing how much difference there is. Guess we will never see a hot Damn 300 tune for the 6.7 or a KEM 345 tune.

Give them time. The tuners are still figuring out the 6.4 and it has been out for years.

i was wondering the same thing.. i hope they figure it out so someone can actually keep up with a 6.4 haha. i also think the turbo on the 6.7 will be the killer of it.. why didnt they go back to the dual turbos?

I beleive I remember reading somewhere that the 6.7 cannot make the same power as the 6.4 right now because the stock fuel system is pretty much maxed out at the +150 hp that the tuners on the market give you right now. maybe someone from H&S or Spartan should jump in and let us know?

Fuel and air seem to be lacking. Not sure which should be upgraded first. Only time will tell.

The fuel system will support 520ish HP for a bit and runs out of fuel (I hear). Several are working on this.

Other than the ID twin (stock +1) turbo kit, does anyone make a single replacement turbo?
