2010-2018 Cummins CCS MM3 Custom Tune Files

What does the Transmission tuning do?

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.

My truck is heavily modified, will this tuning work?

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!

I have an MM3 installed in my 2015 6.7 and am wondering what information is required to be able to get custom tune files?

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.

Can these custom tunes be used on a RaceMe Ultra? After more modifications are made?

Yes.

Are the lope and whistle tunes available for a 2012 6.7L

Yes

Will this work with a raceme platform for a heavily modified truck?

No, the tune files are not compatible with the raceme platform.
