Your VF115 SHO engine will now have 152hp whilst also using less fuel on average than a stock engine!
Not worried about the cost of fuel?
Then enjoy the extended range with that extra fuel left in the tank!
Please note that installing a Nizpro tune WILL NOT correct any existing faults with your engine.
*Performance Caveat:
Engine must use Minimum 87 AKI US gas /91 RON AUS Octane fuel & have adhered to recommended Yamaha service intervals.
