The 6.0 will still beat the 6.6. Even with EFI Live your still not going to be able to run a high setting without Limping your Allison Trans. I ran the Eric's Extreme Race Tune on my 6.0 and it would MOVE. It also removed the Govenor because id had mine to 120+ several times.

 

speed = money the more you have the faster you go

 

aint that the truth wish i had more too

 

i think the dmax will trear a hole in that 6.0. a mild efi tune will still give him +400hp vs lets say the fords makes 350-390hp on race tune. 6.6 by a long shot

 

I think you should race em and see who wins

 

Race and see. I'll tell you now, load a big tune, and only race a 1/4 mile or something with that dmax. Lock out o/d and the trans should be fine. I run almost 500 rwhp through mine, and the stock trans is living, just don't let it nail that 5th gear shift wide open or it will limp. My trans is coming soon though, with some 550 rwhp+ tunes

 

im gonna have to say that the 6.0 would be far ahead

 

7.3 all the way

 

im with 07redsled... ford should take the launch and the dmax start pullin soon after... and im not tryin to top you redsled but i got a buddy with a 06 dmax that we got to 143mph but then again he has quite a bit done to the truck but stock gearing, the speedo was pegged so we started watchin the gps

 

my brother has a 05 excursion mild tune and a 06dmax that has about the same things done. Not sure if it helps, but we raced each other in them and dmax lined me until about 45mph to 70mph i caught him and then he pulled off till we had to get out of it. I would say the dmax
