You can't make turbos smaller with tuning lol.

Lolz I love the curveball of having the event at elevation.

Couldn't agree more with that statement sir. I am curious if that power band and lag is with spray?

Below 2500 rpm is dead. On the street also, below 2500 is zero power and smoke.

Wow, sounds like the Denver elevation wins again. Going to get interesting in the trailer race and sled pull......

Nitrous. Lots and lots of nitrous!

Wayne · May 4, 2014

hopefully you have a nitrous program that will help it spool if the converter isn't loose enough

otherwise.....

Dan, as long as you are happy that is all that matters. Good luck in the competition!

Am I the only one that doesn't think 2500 is horrible for the size of the turbos and the elevation? As long as the converter is loose enough..

Not saying it's ideal, I may be out of touch, I'm used to driving a laggy truck that I don't tow or pull a sled with.

The question is what rpm range it's fueling to. Doubt they have much room

I suppose a 6 speed trans won't help that.

Either way, I bet there will be more than a few trucks that won't be spooling until 2500, I know mine wouldn't at that elevation, and I have a puny single.

It has nothing to do with the trans. Tuning on the 6.7 hasn't come as far as any previous motor that I know of

Well you mentioned the window of the powerband, having 6 shorter gears makes that window smaller.

Personally I only drag race so I'm not a fan of more gears to shift through. These 6r's are doing some great things so I'll just watch and see what happens. For all I know it could be the factor that makes this setup more viable.

Glad you are happy, Dan. Good luck in the competition, and enjoy that truck afterwards too.

It was still fueling at 4200rpm even though power peaked at 3950rpm. I took it to 4500rpm on the dyno. When we were blasting down the streets it was at 4500rpm a good portion of the time.

See that's why I'm a nobody. Congrats
