Just bought a 90ps T200 swb in the summer, very pleased with it after my previous Berlingo!
Theres plenty info on
http://fordtransit.org/forum/ , they reckon the 75ps is underpowered and judging by my 90 I would be inclined to agree.
A few weeks ago I got mine mapped and it now feels similar to a Combo 1.7td in terms of acceleration, well worth the money. Got it done here
