I Would have my doubts on pushing another 70kw from the engine without any hardware changes. The clutch, turbo and stuff are definitely not prepared for that extra load just by a software change.
I contacted a very decent Dutch tuner and they can pull out around 35-40kw with a proper engine specific ECU stage2 tune.
And I think that also is the case because in The Netherlands they dont sell the 180bhp diesel but it's downtuned to 150bhp.(due to emission and laws)
