Bang for buck the Wolf is O.K. The top end power will be pretty much the same if it's a Wolf or any other computer - it's the tuning effort and the base engine that are going to determine how it goes.
Aiming for 170rwkW is something - but you will give the tuner the car, he will give it the fuel and ignition that it needs to make best power and the dyno will give the number - and it all happens in that order - and you just can't get away from it.
Go with the management that your tuner likes to use.
BTW - I run Wolf version 3.1 and I will run Wolf version 4 when I can afford it.
