  • Warranty. Modifying your ECU may void some or all of your manufacturer's warranty.
  • Risk. Increased power adds stress to the engine, transmission and drivetrain. Snizz Performance is not liable for mechanical failure, damage, or injury resulting from the use of a tune or from the condition of your vehicle and parts.
  • Estimates. Power figures are estimates. Actual results depend on your vehicle, parts, fuel and conditions.
  • Licenses. EcuTek ECU and phone flash licenses are tied to your vehicle and are non-refundable once purchased.
  • 30-day limit. All tunes are null and void 30 days after delivery. Revisions, adjustments and any claims related to the tune must be made within 30 days.
  • Refunds. Tuning services are non-refundable once calibration work has started.
