Client Testimonials

Eric J.

“My Cascadia was stuck in limp mode and wouldn’t clear the regen. These guys came out, ran diagnostics, forced a regen, and cleared the codes. All within an hour. Saved my load.

Marcos V.

DPF light wouldn’t go off, and the engine derated mid-route. They found a failed DEF sensor, replaced it on-site, and ran a regen. Back at full power in no time.

Lauren R.

“They manage our entire fleet’s regen schedule. No more surprise breakdowns or DPF fines. Game changer.
