2010-2018 Cummins CCS MM3 Custom Tune Files

Yes! Randy's Transmission recommends our tunes because they are able to meet there requirements.

No.

No, TCM tuning is available as an add-on HERE. These are delete tunes for emissions off trucks.

A stock read is just a copy of the original factory software stored on the ECM. We need that to make sure we have the right base file starting point to get you the correct tunes! Check this page out HERE, for detailed instructions on how to pull a stock file!

No, the tune files are not directly compatible with a RaceMe Tuner, they're specifically for the MM3 platform.

If you order all tunes you will receive multiple tune levels (Stock, Tow, Street, Performance, Race). Once purchased you can reflash your track as needed without additional charges. Custom revisions would need to be purchased at an additional cost.

Absolutely!

You'll need to supply us with a stock read file of the truck, and then we can write the tune files for you.

Level 1 (Tow): ~45 HP / ~100-150 TQ. Level 2 (Daily): ~75 HP / ~200-250 TQ. Level 3 (Performance): ~90-120 HP / ~300-350 TQ. Level 4 (Race/Hot Street): ~120-150 HP / ~400-500 TQ. Level 5 (Max) ~160HP+ / ~500+ TQ.

The MM3 would do the trick, if you've already got the tuner you'd just need the custom tunes written to the specs you're after. If you select all tunes you'd be able to specify having an economy tune written as well as a tune that will give you max hp and torque. You could consider adding a SOTF as well to seamlessly switch between the tunes.

Yes, your existing tune can be modified to accomodate a non-VGT turbo./

Yes we can! As long as we have the list of all the mods and what you're wanting from the tunes, we'll make it happen.

Without the proper supporting modifications you're risking it for sure.

To pass emissions, you need a stock or emissions-compliant tune, but if your truck is deleted, you will need to restore emissions components first.

Yes, high idle can be added to the MM3 custom tune.

Yes, you would need a tune or the truck will have warning lights surrounding VGT issues.

No, you'd have to get a new tune file as the idle is written into the base of the tune.

If you want to switch between different power levels while driving, yes.

The "Service Exhaust" message typically indicates an issue with the tune or emissions system. Checking for DTCs, reloading the tune, and logging data can help resolve the problem. If needed, contact us at tunes@dirtydieselcustoms.com and we can help you troubleshoot!

We require the following:

1) VIN #

2) Tune Level selection (if purchasing a single tune)

3) Any modifications your truck may have (EGR delete, bigger turbo, Injectors etc). The tunes will be written according to what is inputted in the "*MODS" script box, so the more information the better.

4) Tire Size

5) Stock read file.

Yes.

To get idle sounds on your MM3, you'll need to request a custom tune that includes sound modifications from your tuner. This typically involves adding a "sound tune" or exhaust tone adjustments within the custom tune file.

2007.5-2023 Cumming MM3 CCS TCM Tuning Add-On

TCM Tuning increases the line pressure, this puts more pressure on your clutch packs and prevents them from slipping which can cause excessive early wear on 68RFE's clutch disks. It will also change the shifting points to match the new tuning which helps improve the overall driveability.

You bet! These will work on any Ram with the 6.7L Cummins.

Yes, we can have these tunes written to accommodate any modifications that your truck may have. We just ask that you state any modifications in the "*MODS" script box. We will have the tunes written according to what is in this box, so the more information, the better!
