Choose a factory-pump Stage 1–3 tune or a higher-output configuration matched to a Turbo R conversion fuel pump. Injector and wastegate choices follow the selected calibration.
Every package includes your selected FastUTV calibration, RTD4 tuning interface, correct Can-Am adapter cable and required licensing.
Package choices
-
$799: tuning, RTD4, cable and licensing with the stage’s required injectors already fitted.
-
$1,499: the same package plus three new, matched 1000cc injectors for a big-injector stage.
-
New wastegate: +$299 when selected for a big-injector stage. Reusing a suitable installed actuator adds no parts charge.

Octane ratings are US AKI. Select one fuel-specific calibration. E85 stages require fuel matched to the calibration’s ethanol content; gasoline and E85 files are separate. These are fixed-fuel stages.
Supporting hardware and setup
Factory-pump Stage 1–3 retains the original pump and injectors. Higher-output stages require the Turbo R conversion pump and corresponding calibration. Every big-injector stage also requires a matched upgraded wastegate. Keep the factory intercooler and turbo.
Set wastegate pressure and spark-plug gap to the delivered file’s instructions. Correct clutch setup is recommended to make use of the selected tune. Exhaust, clutch parts and other separately quoted build components are additional to the selected package.
Multi-map controls and upgraded-turbo builds require a separate build review and quote. Contact FastUTV with your hardware and fuel details.
WSRD charge tube and blow-off valve
Select the WSRD silicone lower charge tube, $189, with an optional WSRD blow-off valve for $249 more ($438 for the tube and valve selection). Choose the existing intercooled-model configuration. This optional hardware is purchased separately from tuning.
Choose color, upper-tube and valve options on the WSRD product page. Its current availability and any backorder terms apply.
