Try posting in the diesel forum. I'm guessing the advice you need lives there more than here.

Maximum fuel delivery (ie. Fuel delivery at full throttle) is increased by winding out the fuel-stop.

Here's the "stop capsule" on my BJ40.

If you have an HAC (High Altitude Compensator) fitted instead of the stop capsule, then you just wind that out instead:

I understand this is all most people do when they fit a turbo...



(I don't run a turbo.)
