WAKE UP YOUR CUMMINS
Your Cummins didn't leave the factory showing you everything it's got.
Our Custom EFI Live Tuning for 5.9L & 6.7L Cummins gives you the power, response, and drivability you're looking for — with tuning built around your truck, your setup, and how you actually use it.
Go with a Single Tune and keep it simple, or step up to CSP4/CSP5 and put multiple tunes at your fingertips.
ONE TRUCK. MULTIPLE PERSONALITIES.
With CSP tuning, there's no need to drag out the laptop and reflash your truck every time you want something different.
Turn the switch. Pick your tune. Send it.
Depending on your model year, you'll have 4 or 5 tunes available on the fly, letting you change your setup whenever you want.
TUNING OPTIONS
Single Tune | 2006–2021
One custom tune built for your truck and your selected setup. Simple. Effective. Done.
CSP5 | 2006–2012 & 2019–2021
Five selectable tunes available on the fly.
CSP4 | 2013–2018
Four selectable tunes available on the fly.
Going CSP? You'll need a compatible CSP4/CSP5 switch to change tunes on the fly. Single Tune setups do not require a switch.
WANT THE 68RFE DIALED IN TOO?
Add custom transmission tuning to your order for supported 68RFE-equipped trucks.
Because adding power is a hell of a lot better when the transmission knows what to do with it.

This listing is for CUSTOM TUNING ONLY and does not include an EFI Live device.
You'll need a compatible EFI Live device to flash the tune into your truck.
If using an AutoCal, it must be linked to Dynamic Calibration before our tuning can be installed. If it's currently linked to another tuner, don't sweat it — we'll help you figure out what needs to happen.
Quit driving it like it came from the factory.
BUILD YOUR TUNE. FLASH IT. LET THAT CUMMINS EAT.
