Holley’s 2026 LS Fest East coverage shows why data logging, heat control, chassis setup, brakes, tires, and swap packaging matter as much as horsepower.
HP Tuners now supports 2026 Corvette ZR1X ECM and TCM tuning. Here is what owners and shops need to know about Global B controller upgrades, MPVI4 and RTD4 hardware, licensing credits, and a disciplined calibration workflow.
A flex-fuel sensor tells the ECU what is in the tank, but safe performance depends on fuel-system capacity, injector headroom, pressure control, calibrated timing and boost blending, and fault protection. Here are seven checks that matter.
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.
PRI recently spotlighted Stanadyne's 150-year anniversary. We look at what the company's modern RGX 12mm high-pressure GDI pump means for boosted and E85 GM LTx builds, why high-side capacity is only one piece of the fuel system, and how to validate the combination on the dyno.
A higher or lower dyno number does not automatically mean a car gained or lost power. Learn how correction factor, weather, heat soak, gear choice, test procedure and hub-versus-roller hardware change the result, and how to compare performance honestly.
Modern performance cars may require ECU or TCM unlocks, gateway cables and licensing credits before calibration can begin. Learn how to identify the correct access path, budget the full tuning process and avoid buying hardware that cannot communicate with your vehicle.
Some bolt-ons are safe to install and enjoy. Others can create lean fueling, knock, misfires or unnecessary risk before the first hard pull. Learn what actually needs tuning—and what usually doesn’t.
