Maptuner X Features and Benefits:
2) RIVA GP1800 Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.
3) RIVA Intake Manifold Upgrade Kit is installed. Precision tapered billet sleeve directly replaces restrictive mesh element in intake manifold enabling engine to produce more horsepower through increased air flow and boost pressure (+1PSI).
4) RIVA Stage 1 Engine Cooling Upgrade Kit is installed. Kit improves water flow to Yamaha SVHO engine and intercooler for improved performance & reliability. Greatly reduces loss of power due to "heat fade" on stock and Stage 1 modified craft.
5) Solas Concord Impeller is installed. New design incorporates a large blade area and superior hub design that deliver increased acceleration and top speed. Billet nose cone included.
Note: We also offer Solas 13/18 pitch impeller (YV-CD-13/18) that produces approximately 300 more RPM than 13/20 pitch impeller (YV-CD-13/20). Although target RPM for this kit is 8100, RPM is often reduced by high altitude operation or extreme ambient heat and humidity. 13/18 impeller can be utilized to achieve target RPM under these extreme conditions.
6) RIVA GP1800 Performance Ride Plate is installed. Our ride plate increases top speed and significantly enhances handling characteristics.
