The Stage X tune is designed for race level applications and nothing is off the table. It builds on the requirements of the Stage 3 and is intended for engines utilizing at a minimum forged pistons and connecting rods. Each Stage X is specifically tailored to your engine whether it includes a ported and polished head, high performance cams or Garrett/EFR turbocharger. Customization of this nature will require multiple data logging and dyno visits but it is worth the wait. Wheel horsepower can easily be expected to reach 300 HP and beyond. Each Stage includes three performance maps so you can pick and choose your power level and options you want activated.
Full customization to include 100+ octane fuel and/or methanol injection are not only included but highly encouraged.
NOTE: Stage X level tuning is only available on Mini Coopers at this time.
