Nizpro ECU Tune - Yamaha 150 SHO
If anyone is considering the nizpro ECU tune on their Yamaha 150 SHO but struggling to find reviews on this specific motor - DO IT. The increase to 231hp is way more significant than I was expecting. The throttle response is far superior and the engine just sounds like it’s running better.. significantly increase the low end torque. Even my wife noticed it and she hardly pays attention.
I have a 2022 Sportsman 212 with a 150 SHO on it and initially I felt underpowered but this seems to have completely resolved that issue for me.
Very happy. I shipped mine to Tampa Marine Tuning from California; it was super quick and they were response. Mailed it to them on Sunday, received it back on Thursday.
