Even though the 6.7s only have one turbo will they still be as fast as the 6.4's in the end when all the high horse power tunes get finalized and everything? And how is the fuel milage with a straight piped and tuned 6.7? Even with my 40s and lift i still get 15 to 16 mpg all around with my 6.4... Just want to make sure im making a good decision before i sell my truck.
