HP Tuners’ new NHRA contingency program covers four Sportsman classes. Here is what racers should verify about payouts, proof of purchase, decals, vehicle documentation and pre-race preparation.
Hub dyno vs. chassis dyno testing is about more than peak horsepower. As power climbs, load control, repeatability, fuel pressure, lambda, ignition timing, boost, temperatures, throttle angle, and torque management become critical to safe calibration. This technical guide explains why direct-to-hub testing can remove tire-related variables, how to compare dyno results correctly, and why NTHP's Mainline ProHub 3000CCS is useful for high-horsepower validation, diagnostics, and tuning. It also connects the industry's growing emphasis on engineering and professional service technology to the way modern performance vehicles should be developed and tested.
HP Tuners has added direct OBD-II ECM and TCM tuning support for the 2025-2026 Ford Mustang GTD. Here is what the new access, licensing requirements, and data-logging capability mean for the 815-hp factory supercar.
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.
