I also found that i had fault code 00550

i tried changing the 3rd injector sensor, and that didn't solve the probleme.

Eventualy ( yesterday ) i changed the injection pump, and that solved the probleme.

I would try measuring block 11 to see how boost is behaving, sounds like you have a leak or something which is resulting in excessive fueling. You can drag/drop .csv files onto our website as well to graph them and then zoom in/out as you please.

MAP should go up more towards 2 bar, or 14.5 PSI.
