I have seen a car with the fuel cut relay which would stumble and misfire well below the limiting speed.We disconnected the relay and it ran cleanly to redline so we installed a rev limit rotor available from a turbo instead
That wouldn't be a 91161713600 would it?

Do you have a pn for the row turbo you referenced?

Thanks
