MK SD33T Boost increase - Fuel increase? how?

Post by r32wa »

I have the turbo side of things sorted out no drama but how do I increase the fuel to match the boost? Not looking at running huge numbers just 10 or 11 psi but with out fuel air on its own is useless. Does the pump have any adjustments on it and where are they? I tried a search and it says plenty about increasing the fuel but not how. Any help be greatly appreciated.

G'day Mate i take it you have a factory turbo engine with boost compensating injector pump and want to increase the fuel? Anyhow i got some pics of the non-turbo pump but im pretty sure that the governors are the same. As for how far to move it anti-clockwise i think to richen. I stated too far with black smoke and worked back from there until only small amount to smoke was seen under full load. But someone will know how far to move it who has done it a few times Image
