Discussion
There are several options open to you but it has emerged that some tuners run excessively high boost pressures on their D5 maps to get their quoted outputs, which it turn seriously compromises the longevity of the turbos and other hardware components. The MTE remap from Kalmar Union seems to be the most mechanically sympathetic remap out there but if you want to know more about what some owners have found about the various tuners' offerings, it would be a good idea to have a look on and maybe post the same question on the High Performance Volvo Club forum (www.t5d5.org).
