Nizpro 332hp ECU Flash Yamaha SHO / Offshore

The Nizpro ECU Flash is a cost effective, simple way of turning your engine into a 332hp monster: improving hole shot, mid-range acceleration and top speed. Cruise at your normal speed with lower revs and less engine noise with improved overall fuel economy that has an average increase of 3 - 8%

An ECU Flash is about optimizing the performance of your engine. It’s not about turning your boat into a rocket ship – that’s what we made Nizpro 450s Superchargers for!
