Hi All, any info of help on this would be appreciated.

Got this in and starts, runs ok at idle and most of the time on roadtest.Then all of a sudden loses power, no acceleration will not rev over 3500-4000 rpm (60mph).
checked fault codes with texa and comes up with MAF,Turbo pressure,(P1521)clutch pedal switch & (P0380)Glowplug circuit.
Changed MAF still same...
Can't find any other data to check anything else., anyone got any ideas?

Thanks

Paul
