QUESTIONS & ANSWERS
Ask a Question-
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 efi live autocal but the company I bought it from is no longer in business. How do I unlink this to install new tunes?
Unfortunately, there is no way to unlink it if you cannot get ahold of the previous company. You would need to purchase a new autocal in order to get new tunes.

i have efi live tunes with another tuner for my 19 HO ram 3500 can i just order your tune to try or do i need something from the other tuner?
If you are using an Autocal to flash the truck, the autocal will be linked to whoever tuned your truck previously. You would need to contact them, get unlink codes (no charge) and then that will free up the autocal to allow us to link to it. Once that is completed, yes you can order tuning and you will not need a license as you have already licensed the truck to the autocal. Hope that makes sense!

How much additional money is the autocal device to install the tunes or is it included
The Autocal is not included in this part, you would need to go here to order the tune files with Autocal. https://www.dirtydieselcustom.ca/products/2010-2018-cummins-efi-live-autocal-ccs-tunes

I see a “single tune with no Vin license” option. Is that a generic tune?
No this is any tune you'd like, you just would not get a VIN license with that tune. So you'd need to have available licenses on your autocal or have already licensed the truck in order to use the file.
