Otherwise, as you have had new injectors fitted (I assume correctly, and that they were set to the correct opening pressure for the pump) then the only other thing is the pump internal control. Don't know which pump you have but some have a diaphragm which senses turbo pressure and increases the fuel supply accordingly. This might have gone out of adjustment. I had a 405 turbo which showed this problem, and was able to adjust the spring pressure under the diaphragm to cure it. It could be that this spring has weakened, but it would be unusual. If your model is fitted with an EGR ( Exhaust gas re circulation) valve - check that it is not sticking - you will more than likely have to remove it to check - if it is and it will free off great - if not replace it - if it is working ok then try blocking off the vac pipe going to it - then give it a good thrashing to clear it out - hopefully this will fix the problem !
