Model-year 2027 brings a major change to regulated vehicle diagnostics. Here is what OBDonUDS, secure gateways, module access and modern data logging mean for tuners, shops and late-model performance builds.

SEMA’s 2026 market data says internal-combustion vehicles are expected to remain the dominant new-vehicle powertrain through the next decade. Here’s what that means for enthusiasts building boosted, fueled, tuned and track-ready performance cars.

Race fuel selection is about more than the octane number. Learn how AKI, RON, MON, oxygen content, ethanol, lead, stoichiometric ratio, fuel-system capacity and calibration work together.

Horsepower claims can be useful, but only when the test method, baseline, fuel, calibration, temperature and supporting parts are disclosed. Learn how to separate a meaningful before-and-after test from a headline number, and how to choose upgrades that work together on your vehicle.

Lambda keeps fueling targets consistent across gasoline, ethanol and changing E85 blends, but only when the wideband sensor, ethanol-content data and logger scaling are trustworthy.

A larger heat exchanger is not always the first answer. This diagnostic guide shows how to test supercharger intercooler-pump operation, air pockets, IAT2 rise, cooldown recovery and the actual limit in a liquid-to-air cooling circuit.

A 1000cc injector rating does not tell the whole story. Learn how fuel pressure, boost, E85 demand, impedance, dead time, physical fitment and tuning data determine whether an injector is right for the build.

Modern performance cars may require controller services, gateway cables and licensing before calibration begins. Learn how to identify the access path, budget the hardware and validate the vehicle safely.

Ford’s new 5.4-liter Coyote-based Hypercar has fired in the chassis and begins European testing in August. Here are six endurance-racing lessons Mustang builders can use to create more durable, repeatable power.
