Any diesel experts out there?

I'm looking at a replacement for my car with the following work done on it (it's the 2.0 turbo diesel 2004 rover) -

Engine:
SDi injectors
Donny stainless turbo outlet pipe
custom ported inlet manifold and charge pipe
Roose motorsport silicone boost hoses
Large universal double cone filter
MAFAM on standard Bosch MAF
Wingspeed Decat pipe
Powerflow backbox with oval tailpipe
Boost upped to around 20psi
Custom Reidy Remap - RR'd at 158bhp (now the MAF has deteriorated a bit it's probably running slightly less but its a lot less smokey!)

Has anyone got thoughts as to whether this can be a reliable set up?
