Cummins X15 Efficency Series Power / Fuel Economy Tuning

Finally Custom Tuning solution for the 2018 - 2023 Effiecency Series X15 Cummins! 

This Custom Tuning Service takes about an hour, we will send you a laptop and all the connection cables required to simply connect the laptop to your trucks diagnostic port and with a couple clicks our tech's can remotely and get your tuning taken care of quickly.

Based off of your ENGINE SERIAL NUMBER we can tell if your Efficiency Series engine has the larger or smaller turbo from the factory. Some of these CPL numbers use a smaller turbocharger that from the factory ranged from 400hp/1450tq - 500/1850tqhp.

The engines equipped with the "smaller" turbo setup can reliably produce 500hp and 1850TQ! For customers wanting maximum power they are capable of 550hp 1950TQ!

It is VERY important to have the ENGINE SERIAL NUMBER ready when calling for more details so we can help assist you in a timely manner.
