Just wondering how things are progressing at Spartan and/or with Nutty on tunes for the 6.7.

Also, is Mick still at Spartan? Haven't seen him post anything in a while.

There must be some issues because it's been about a month since the initial dpf delete tunes were being shown...

there are talk of beta tunes at PSN up to 585 RWHP. Then they run out of air

What causes it to run out of air? What's the fix?

ok, so the fix would be to interchange for a different turbo to achieve the higher gains or is there a simpler fix?

Upgraded turbo will be your best bet. I don't know a whole lot about these engines tho, I would assume you need to upgrade some internal parts when running that much HP.

this is all hypothetical talk anyways since these are just rumors about the tuning...I'm just curious. I read in one of the diesel mags, that this turbo was supposed to be top knotch. Guess we'll have to wait and see. Thanks for the input

The turbo in the 6.7 is supposed to the new technology of turbo design. The single turbo with the dual wheel idea could be a huge thing for the future of moving air. One of this size just won't move what aftermarket units will. There has to be room left for the aftermarket.....the issue will just be making room for the aftermarket lol

well said, it's going to be great once aftermarket companies start doing exactly what you said...a bigger, better, and higher performance turbo w/ the same design to be direct swap :D

I would think the internals would be fine. I'm sure Ford didn't want a stock turbo making 650rwhp. If it was capable they know guys would run them at the level. Either way pretty amazing these 6.7l are making that kind of power this early.

Put it this way, none of the big 3 would make the newer trucks to be any less of a truck than the previous model, by rights. Take for example the evolution of the diesel trucks and diesel market since the mid 90's. First the 7.3, then the later 7.3s, then the 6.0 (which really doesn't count reliability-wise LOL), then the 6.4, now the 6.7. During all this time, the powerplants on each new design has been capable of more and more power with each new design. Comparing apples to apples, put a chip/programmer, intake, and exhaust on each truck. The 7.3's were what... 300 some odd horse tops?!? Then the 6.0s were capable of mid 400s, then the 6.4 would make 550 on fuel alone! Now why would they build the new 6.7 with a new turbo design and have it only support 580ish horse when it could support 650-700? Of course they don't want those of us in the aftermarket world to do this to their trucks because of course it is going to cause them warranty headaches, but they know we will. Ford, GM, and Dodge are all trying to encode and lock up the ECM's so we can't mess with them... They are getting smarter... but so are our tuner guys in the aftermarket world! Until the big 3 all hire Genius German Engineers, our backwoods need-for-speed hotrodding tuner guys will be right there... breaking into the sophisticated ECMs of these new trucks! Keep up the good work guys!:thumbsup

I agree GOSsteel.


Just give it patience, hell, most should be happy to see they are taking time and hopefully getting together a solid set of tunes before releasing for sale. Wouldn't be good business to see a bunch of new 6.7's blowing up and costing big coin to fix.

Was talking to my bro which is a manager at a Chev dealer. They had a conference with reps and were told last year that by 2012 Ford Chev and Dodge were all going to be traceable if the truck was tuned. This will affect trade, resale and obviously warranty. But like you guys said there is a lot of smart people out there and I am sure some one will figure it out.
