E270cdi + chip
Most of the guys in here are not familiar with the diesel engines we use in europe, but they may be able to give you advice on flashing in general.
But whatever you do, don't buy a chip (an external box). Go for a flash (reprogramming of the software).
the torque I don't know about, but I think it will be OK. My 220CDI (143hp) can be flashed to about 175-180 hp with no problems (about 22-26%)
Maybe you can have a talk with your dealer

btw, I would personally not do the flashing with a company who don't know how much my engine and trans can take. How do I then know they know what they are doing?
