Emissions systems that actually work beat emissions systems that are gone.
Turbo, EGR & Emissions
Most emissions complaints are not the emissions system's fault. A leaking boot, a sooted turbo vane, a lazy sensor or a truck that never gets a highway run causes the regens, and replacing a DPF does nothing about it.
We diagnose the whole air path — turbo, charge pipes, intercooler, EGR, sensors, aftertreatment — and repair the cause. Everything is kept legal and street-registerable in California.

How we work it
The four steps, every time
- 01
Air-path test
Smoke test and boost logging locate leaks before parts are considered.
- 02
Soot assessment
Backpressure and soot-load data show whether a DPF is truly plugged or just reporting.
- 03
Repair
Clean, calibrate or replace — in that order, based on measured condition.
- 04
Regen & verify
Forced regen, ash-load reset where applicable, and a validation drive cycle.

Questions
Straight answers
Will you delete my emissions?
No. It is illegal on a registered California vehicle and it kills resale. We make the factory system work properly instead.
Why does my truck regen so often?
Short trips, a boost leak, a stuck EGR valve or a failing sensor are the usual causes. We find which one applies to your truck.
Can a DPF be cleaned instead of replaced?
Frequently, yes. Ash-loaded filters can be professionally cleaned at a fraction of replacement cost.
