2006-2021 Cummins CCS EFILive Custom Tune Files

Great tunes

Quick delivery

The CCS tuning feels great compared to my previous custom tune. All temps and pressures are safe and EGT’s even improved with the added hp. Truck runs smoother in all ranges and sounds much better as well. The DDC tuning support (Kyle and Spencer) were a big help, and always replied to me in a timely manner with effective insight. I would highly recommend this if you’re in the market for a custom tune.
