Precision EFI reflashes for Arctic Cay/Yamaha 998


Stage 1 brings your sled up to 230 horse without changing any parts. Throttle response is double and includes the Precision EFI knock system

Stage 2 is 250 horses with the same increases in throttle response and knock detection system. This tune requires a 2.5 inch muffler, minimum and will also require additional weight in the clutch.

Stage 3 is 280 horses and the maximum performance from the stock map sensor and injectors. Again, 2.5 inch muffler and clutching changes are required.

Multimap includes all 3 stages, plus an economy map, launch control and the dash flash
