What to know before you book in Irving
- Emissions-legal only: we never relay delete tunes, defeat devices or catalytic converter removal
- Dyno sessions document before-and-after power so you can see what a tune actually changed
- Ask how the shop handles warranty concerns and whether the stock calibration is saved
- Turbo and E85 builds need custom calibration, which costs more and takes longer
North Texas summers routinely push past 100°F, the sun is intense most of the year, and spring brings some of the most frequent hailstorms in the country. Drivers in Irving put most of their miles on SH 114, SH 183, Loop 12 and I-635.

Emissions rules for tuning in Irving
- Irving is in Dallas County, part of the Texas emissions-testing area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall and Tarrant counties). Gasoline vehicles 2 to 24 years old need an annual OBDII emissions test.
- The test checks the OBD system and readiness monitors, and an inspection looks for required emissions equipment such as the catalytic converter. A tune that disables monitors or equipment can make the car fail.
- Federal law (the Clean Air Act) prohibits removing or defeating emissions controls in every state, including with software. PitRelay only relays emissions-legal work.

Tuning itself is not illegal, but any tune that removes, disables or defeats an emissions control is illegal under the federal Clean Air Act in every state. PitRelay only relays emissions-legal work.
Will a tune void my warranty?
It can affect warranty coverage on related parts. Ask the shop how it handles this and whether the stock file is saved so it can be restored.
