Technical Specification & Calibration Information

  • Master Software Calibration: Unlike setup shops using locked slave tools, we hold genuine master licenses. We inspect and modify your engine's code directly via EVC WinOLS, providing full transparency and bespoke adjustments.
  • Data-Driven Precision: Extensive datalogging is integral to our workflow. We log live parameters prior to tuning to assess health, and continue monitoring during dyno runs to confirm optimal air-fuel ratios, boost parameters, and thermal safety limits.
