All pricing is indicative of your booked Back to Back (B2B) session. Packages can be combined. Final cost depends on your specific vehicle configuration and requirements.

Booking Requirements: All tuning requires a booking with us for delivery via Track, Road, or Dyno tuning. Booked sessions start at 3 hours for stock engine and turbo, 4 hours for upgraded turbo packages, and 6 hours for built motor packages. Port Injection Add-On adds +1 hour to your booking time. Additional Map adds the same amount of booking time as your base purchase. For Dyno sessions, we recommend you are setup and ready to go on the Dyno 30 minutes before your time with us. You are charged for the full booked time regardless of when your tune is completed. See our refund policy for full details.

Rebooking & Retune Fees: Exceeding the scheduled time slot or rescheduling with less than 24 hours notice will trigger a rebooking fee of $300 AUD. If we must stop tuning due to a mechanical issue, a retune fee will be required (you only pay the retune fee, not the rebooking fee).

Mechanical Issues & Service Suspension: We reserve the right to immediately cease tuning services without refund if mechanical issues are discovered or if your vehicle does not meet our quality standards. Any resumption of work may incur additional charges. See our Terms & Conditions and Tuning Disclosure for complete details on our policies.
