    Basically because the DTI and CDTI are very different in design. The CDTi has a much higher diesel pressure, better combustion = more power.
    Now I need a turbo to keep up!

    c = common rail, its a high pressure injection and a high pressure turbo, you can remap the 2.0 to about 125 bhp but itll cost a few quid (£300 about)

    Best car to get modified is teh 1.9.

    The 2.0 DTi is an underpowered engine for the C chassis IMO.

    A remap helps but the 1.9 dances around the 2.0 and the 2.2.
