Baseline runs capture your car’s current reality, revealing underlying maintenance issues before any changes. Heat soak can exaggerate or hide improvements, so reputable shops regulate temperatures and timing between pulls. Consistency matters more than chasing a single peak figure. By normalizing conditions and documenting every step, you get graphs that tell the truth and translate cleanly to repeatable, everyday performance.

Watch for comprehensive logging: ignition timing, knock retard, wastegate duty cycle, lambda targets, fuel trims, torque targets, and throttle angle. These channels reveal safety margins and how the ECU interprets requests. Smooth curves and stable corrections beat spiky peaks. A careful tuner aims for predictable behavior during part‑throttle transitions, because city driving spends far more time there than at full throttle.

Strap placement, tire condition, brake checks, and wheel chocks are non‑negotiable. Professional operators confirm gear selection, traction control settings, and tire pressures tailored for dyno work. They use trusted fans to shield intercoolers and radiators from heat soak. Fire extinguishers, clear communication, and emergency protocols protect people and machinery. When procedures feel disciplined, you can trust the data and the results.
