Ignore the generic labels pre-populated on the MM3 (Stock, Street, Tow, etc.)
Use keypad "0" for 30HP towing.
“1” for 60HP and “2” for 90HP.
I would not recommend going any higher than "3" 120 HP with your current configuration.

That is precisely what I needed to know; thanks again!
Is it possible to leave the cat or even the whole DPF system running these tunes? (it's off now - straight piped).
The noise and smell caught me off guard. I expected the noise and have a resonator to throw in it next time I get some days off.
You could always throw a muffler behind that if you are unsatisfied, but none of this will keep the fumes out of the cabin.
Several buddies with 5.9s and 6.7s have no DPF or emissions, but they are far more bearable.
I did a CCV delete with the little filter under the hood.
That could be the culprit.
We may backstock on that or at least put a catch can inline on the OEM setup.
It's probably the best bet so I can get some negative pressure on the CCV filter and crankcase.
Adding the factory muffler/resonator back will significantly improve the noise level in the cab.
The rest of the exhaust components must be removed while running the MM3 tunes.
The factory exhaust will clog eventually.
If all the joints are adequately sealed, you should not get any smells off the cab from straight pipe exhaust, so double-check all your fittings and seals.
If I had to guess, it's the CCV delete coupled with the likelihood you are running defrost now that the temperatures are dropping.
There is minimal gain to the CCV delete as long as you change the filter regularly at around 30-40k; most on here will agree that the factory-recommended 67k is way too long.

I'm pretty sure CCV is the culprit.
You're right; gains are minimal.
I'll probably go back to stock with that for sure.
I do like the idea of maintaining the negative pressure on the system.
I may throw an oil catch can in instead.
Thanks!
My tire height is 34.5.
I saw the ability to change tire height in the MM3, so I corrected it to 34.5", thinking it may better calibrate my speedometer.
Shortly afterward, when driving, the ABS light came on, and I noticed my speedo didn't work and just sat on zero.
I also got a red lightning bolt venturi-looking symbol with some throttle service message that I didn't have time to read while driving.
I may try re-uploading the tune again.
When changing tire size, enter it in a four-digit format.
Enter 34.50, and all should be good.

That one zero did it!
Everything cleared up.
No more Christmas tree lights all over my dash.
