Emissions & Tuning Policy
Utah Dyno Shop is a dynamometer testing facility. We provide the dyno, the bay and an operator so you and your tuner can measure, log and verify what your vehicle makes.
Tunes are between you and your tuner
Tuning software and calibrations are written, licensed and supported by independent tuners — whether you bring your own tuner or we connect you with one of our tuning partners. What a tune does, which parts it supports, and whether it is legal for your vehicle and how you use it is between you and that tuner.
We operate the dyno while your tune is tested and adjusted, and we hand you the numbers. Running a vehicle on our dyno does not mean we have inspected, approved or certified its parts, its calibration or its emissions compliance.
Emissions equipment
We do not sell, remove, install or modify emissions control equipment, and we do not sell or install software designed to disable it. That includes diesel particulate filters, EGR systems, SCR / DEF systems, catalytic converters and the sensors that monitor them.
Competition vehicles
Vehicles built for dedicated competition use are welcome on our dyno. If your vehicle is a competition vehicle, you are responsible for its status and how it is used, including keeping it off public roads.
Your responsibility as the owner
- Keeping any vehicle you drive on public roads compliant with federal, state and local emissions and inspection laws.
- Knowing what is installed on your vehicle and what your tune does.
- Telling us about anything that affects safe operation on the dyno before your session.
Our right to decline
We may decline or end any session at our discretion, including when a vehicle is unsafe to run or a request falls outside this policy.
