Sounds to me like a fuel problem. I had a very similar situation, whitish / blue smoke, power cutting out. I'd bet my money its your fuel filter. When I did my one, I changed both fuel and air so I could not elimante exactly what the fault was, but it was definately one of those two, as I no longer have the problem.

Hi guys
Im having a similar problem with 09 gu6 common rail. My simptoms are. At 105 ks the engine looses power untill speed drops them picks up power again. A similar feeling to a speed limited truck. This seems to have started after I had the preasure relief valve repalced after getting clagged up after a bad dose of fuel. I have now changed the fuel filter and added a 30 micron exceedy in line filter after the standard filter.

The reason you are getting the limp is because MAF voltages exceed either 3.77 V under 2,500 RPM when cold or 3.99 V under 3,000 RPM when hot ( engine).
This is well known problem on Di ZD30 with EGR blanked off and boost control bypassed with Dawes/needle valve.
Time to go to next stage which is more advanced but my what a difference it makes again. Search Jaycar voltage modifier and fuel cut defeat module.
Cheers

FDC (Fuel Cut Defender) kit p/n is KC5439.
It is originally for MAP (boost) sensor signal clamping but as luck would have it, it limits signal to max 3.98 V so using it for MAF signal wire is just perfect.
You can try FDC only by splicing it in to MAF to ECU signal wire but best results are obtained having it wired in series after JDVM. That way one can manipulate AFRs and have limp limit.
Standard disclaimer: this is all advanced stuff and can result in damage if you don't understand how these things work and what they do. It is not a rocket science but cautious approach is required.
Regards
