Base Map Tuning Service

We have partnered with Drivehard Performance to bring you a pre-tune checkup and Base Map tuning service. This service is suitable for unmodified engines (catback exhaust upgrade also ok). To book an appointment or inquire further, contact Drivehard Performance @ 604-270-2494 or their Facebook page. Pro tuning is also available if these maps do not fit your needs.

  1. These are the OEM specified power and torque numbers. Please note that rating standards have changed multiple times throughout the years.
  2. Base map performance is measured on 94 octane. 91 octane will deliver approximately 5% less power. Performance numbers will vary per vehicle depending on manufacturing tolerance, vehicle condition, and weather conditions.
