2011 6.7 Mods
 

I have 2011 Cummins with an H&S Performance Mini Max, DPF Delete Kit and 5" straight pipe (turbo to tip) and the truck is extremely quit and makes very very very little smoke. How the heck can I make it loader and generate more smoke????? I also installed a "smoke switch" and it doesn't help much either. Do I just have to take the hit and by an Edge Box??? Would go with a Smarty but I want something I can adjust on the fly.

Don't get me wrong I dont want to go around town smokin up the place but having the ability to dump it out once in awhile is nice. I miss my 05, it was load and rolled the coal when needed.

Any thoughts on glasspacks, I read some threads and most say you wont notice the difference, same with changing out the 5" exhaust for a 4", not much difference in the sound.

Has anyone changed the exhaust manifold and has it made a difference in the sound?

I'd like to keep the stock turbo setup, due to the exhaust brake. Any other ideas on how to make it loader or increase the black stuff ???

.11 tune

Are you talking about the H&S 6.8.11 update? If so doesn't the lastest update include all previous updates? I currently have 6.8.13 update loaded on my truck

Oh wow...not again!

different tune. try the .11

Put in some bigger injector nozzles and stack a TS MP-8 with the H&S. At that point you'll need a bigger turbo. I'm just about to try a 2nd gen manifold and a few different turbos. Just waiting for the weather to warm-up some. You probably can get 600-700rwhp with slightly larger nozzles. I have a set of 35% oversized nozzles. Of course the driveline will complain, but thats the next mod. You might need to put in a fuel rail pressure shim, and modify the CP3 for more volume. I still haven't found the limit of the CP3. Stock with the H&S, there is a small amount of fuel available. The hottest/smokey H&S tune is the **** hot, non turbo tune.

Here is the custom mini tunes.

I have the fuel rail mods purchased at H&S and will be adding injectors and changing exhaust manifold and turbo once I figure out the best ones to go with. Would really like to keep the stock exhaust brake though.

The 10/11 seems to have more CP3 volume than the earlier 6.7L trucks. What size of sticks you thinking about running? I'm going to use a 2nd gen manifold and try a few singles just for kicks. I want to try a set of injectors as well, so I'm going to build-up a set of twins using the stocker.

The real problem with the HE351VGT turbo, if you want a responsive turbo, you're going to have egt issues. Other than the e-brake, I'm not overly impressed with the stock turbo.[duhhh][laugh]

most important question, how does it run? i just ordered the mini max, trans tune, fuel rail shim and dpf delete. just wondering if its a waste of money or if this truck will finally move its edit.

I up loaded the hot dam setup that H&S just came out with. The truck runs great, the sound seemed to go up a notch and it now makes the little cloud of smoke... just what I was looking for

No still isn't fast enough, at least for me. Trouble is it accelerates way better and you start to like it.[coffee][laugh]

Chris, you should just try and keep up with all the changes.[laugh] I'm still working my way thru the 6.8.12 custom tunes.

6.8.15 is out now. I still like the 6.8.11 tune, the best all around street fun, good gas mileage tune.[coffee]

6.8.18 is the tune that cam in my Mini Maxx today!! I also have the latest trans tuning as well as the (4) custom tunes from the site. HOT DAMM Aggressive and No Turbo tuning, and MILD aggressive and No Turbo tuning.

Can someone tell me if I can run any of those custom tunes? Whats the difference?

Hot Damm-agro, have the big (175HP) power tune for the hot setting, turbo VGT set for rapid spool-up and max turbo responsiveness.
mild tune-no agro, have the 120 power tune, no turbo VGT tuning.

Thanks brother. Have you ran one of those yet? Which one can I run?
