you are right on the money there Krewat, just went out in the bay, grabbed the wheel chock from the pumper next to it, flipped it around backward, placed it under the drivers side front tire and tried to climb it in 4 HI, tach made it to just below 2K and she just sat there sweating.
I'd wager that the 6.4 with a tuner would eat that 6.2L for lunch
Honestly that's not much of a wager, or very fair. Tuners for gas generally only make modest gains in power at best, but do a very good job of managing fuel, shift points, etc. Tuners for diesel on the other hand can add stupid amounts of HP and TQ, along with managing shift points, etc.
Yes the 6.2l has a tune, however it doesn't really increase the crank power output by much just allows some more of that power to get to the ground. Compare the GCWR of the 6.4l 3.73 to the GCWR of the 6.2l with 4.30s you will see the ratings are close.
This morning I've tried on 2 trucks and my 2010 musteng to drive in 3rd over 55. The mustang has a manual with 3:73s its not pulling anymore at 50mph. The 04 f150 w/ 5.4l also has 3.73s and is an auto. If I remember right the didn't offer a manual in 04 and 05s. Well in auto it will shift out at 45mph. If I manually shift it'll pull right up to 50 and that's it. My 04 f250 6.0 w/ 4:10s is the same way. Last night I videoed 2 runs and tried again today and its the same way. Ok I'm taking into account cause I don't know but yall say that the v10 can run same speed 1 gear lower. You might reach 55mph in 3rd but I don't think you'll keep pulling. Where as in 4th I get next to 70mph in 4th. This I'm not real sure. I really can't tell if I had just shifted or easied up off the gas lastnight. The video is only 31 seconds long I get to 80 mph within that time pulling 10k +-. My goal is to show my truck pulls past 3100 rpm. 1st shifted at 3500 and 2nd at 3750 and 3rd at 3750. I "think" 4th shifted at 3250 and at 70 but like a dumb **** I chose right then to record my pyro and boost gauges. Like any body cares about 23 lbs of boost. My buddy is going to try it out in his v10 and see what he gets.

That was sort of my point.....
Delete the emision garbage on the current 6.7, or the 6.4 for that matter put a tuner on them and you will outpull any gasser by a long shot......
I guess my point is: That comparison between "Crazy001" and the guy with the 6.2 was not an equal race, too many variables= terrain,load wieght, wind resistance, tuned vs. stock, bumper hitch vs. fifth wheel,......
Get a stock 6.7 and a stock 6.2 with the same trailer and load, down the same road, and you would get a much more accurate comparison.
Posted this in the ECOBOOST thread. But I figured it would give us something new to argue about.
Why not both?
Develpers at the University of Wisconsin-Madison:
They devolped an engine that was a Gas/Diesel Hybrid. Basically they took a diesel engine and through out the fuel curves they programed and added Gas.
The engine Had Near 0% emmisions, And the Thermal efficiency was 60%.
The engine also requires lower injection pressures 7,000ish-12,000ish.
Most current diesels can be converted easily by adding Gas tank, Common port injector and a control module.
NO EMMISIONS EQUIPMENT!! The emmisions on this was Well below current regulations. Bio diesel and E85 is expected to have higher Thermal efficiency. <!-- / message -->
