Re: Loss of top end power
Sounds normal to me.
This engine doesn't start to produce power until after 3000rpms.
The air resistance at that speed is what is holding it back.
WEith my CPI, when I hit 3000rpms and the IMTV valve kicks in, it is like a mini-turbo spooled up and the engine really takes off.
