Real call · I-80 westbound, Grand Island

"Derate hit at mile 312 on I-80, 5MPH limp mode. Cummins shop in Grand Island had a 3-day wait. Moku showed up in 80 minutes, ran a forced regen, found a sticking DEF doser, swapped it on the shoulder. Truck back at full power, finished the load."

Common questions

Can you delete or tune emissions equipment?+

No. Emissions tampering is a federal violation and we won't touch it. We can repair or replace OEM aftertreatment hardware to get you out of derate legally.
