so it looks like this place is earning its name again.

just got my third about a month ago.

mash it from a dead stop, not even loading the torque converter, and it'll get about 15ft out and dust the hell out of the back tires for a couple seconds. even with the 1200lb utility bed on it!! LOL

i need to do the delete/h&s on my old farm truck! it actually seems to have more power than my dodge with the quadzilla...it definitely has less lag!

the 6.7's don't make the power that the 6.4's do when tuned, but you could throw a ~150 tune on it, and it would be a hoot!

An 86, and it's not a 4eye. And Denny, if you think IIs are challenging, I challenge you to diagnose some SVO issues. It's definitely a love/hate.

Good luck getting home sooner.

that's what i've heard...honestly, i'm pretty happy with the power and the mileage, for that matter. i've run through several tanks, and i'm averaging around 18mpg. i've had some really heavy city driving tanks that hand calculated to around 16.5mpg and some heavy highway driving tanks that hand calculated to 19.22mpg. ...with all of that said, another 150hp does sound like fun!

what was the stock 6.4 rated at? (hp/tq)

Been there, done that as well.

We have bought and sold a 2009 GTCS this past year. I still have one Mustang though that I will never get rid of.

those 6.7's will knock down some fuel mileage, that's for sure!

I think they're like 350hp from the factory? 6.7's are 400?

6.7 is supposed to be 400/800

i'm just wondering if the reason that the 6.7 tuned isn't making as much as the 6.4 tuned, might be that the 6.7 is turned up a little more to begin with.

do they have the same transmissions? (6.4/6.7) i like this 6sp!

the 6.7's fuel system can't support as much power as the 6.4's. The 6.4's compound turbo setup really helps too.

6.4 has a 5sp tranny

i looked up the 6.4, and the specs said 350hp/650tq.

do you know if the new 6sp is as strong? i didn't think about the compound turbos...that makes sense.

[Cooter]

6sp should be as strong or stronger

[STANGGT40]

6sp should be as strong or stronger

that's definitely good to know!

big pimpin'! egr/dpf deleted yet?

nice! that thing must be a beast!
