Its a very low state of tune, not much boost as standard, and fairly high compression for a turbo lump I believe....also emissions limited its potential in this application - its £285 tax, you could have more power quite easily but they'd not be at all good on emissions, and how many folk are willing to spend £485 per year to tax a Mondeo.
These 5 cylinder lumps are a fairly old design now, being developed from the 5 pot Volvo engines that date back to the 850 T5 era..the 2.5T dies with the last generation of Focus and Mondeo and has been replaced by the Ecoboost.
Remap to ~250bhp without much bother mind, and loads of torque, a very lazy car to drive. 300bhp is achievable with bolt on bits only, in the Focus world at least.
