Ford TDCi sluggish until turbo kicks in

I doubt this is an ignition or fuel supply problem, those would have very different symptoms. Turbos are air compressors driven by exhaust pressure, modern ones have electronic sensors that measure air temperature, pressure and air flow and feed the information to a computer which controls boost pressure, ignition timing and fuel delivery. If these sensors fail you will usually get a check engine light and a diagnostic code. As you haven't gotten a code the most likely culprits are: Air leaks: there could be an air leak in the intake or output side of the turbo which is causing lost pressure and giving incorrect sensor readings. Check for loose or degraded hoses and re-attach/replace as necessary Stuck Exhaust Gas Recirculation (EGR) valve: An EGR valve is an emissions control device which allows a small amount of exhaust into the intake manifold to help control emissions. As EGR valves are passing exhaust over time they get fouled by carbon deposits and can get stuck open or closed. I
