I'd think twice about stage 3 if you're after a daily commuter. There's a few posts about overboost with the stage 3 and there's no single solution that I've come across. My 56 Aero is now on 150k miles and I have an ever increasing list of issues, some of which I've sorted previously in the 3 years since I bought the car. I use the car daily and have deliberately stuck with the stage 1 as I'm already spending much of my free time just keeping the car on the road - last thing I need to introduce is another source of problems!
I upgraded Fb2 to stage 3 at about 70K miles, and kept it to about 142K by which time it was at stage 4 and the b235R was pretty much maxed out. I have a very different experience and would highly recommend stage 3 as the
ideal road spec B235. Beyond that you're into potential challenges, but only when things aren't 100% right in the first place.
I'd second Fliptop's thoughts ... albeit I've only ever gone to stage 3. But mine
is used as a daily commuter. From what I understand, the overboost issue is limited to the later ("dame edna") shape 9-5's - such as the 2008 model year the OP has bought/is buying - and is down to the wastegate catching on the exhaust housing when it gets warm. Most of the other issues (worn suspension, etc) will affect all 9-5's at some point, bear in mind that the 2008MY car is 11 years old now!
Oh and when I had my (expensive) engine rebuild done on the current 9-5, I had the clutch changed too (because the engine was coming out anyway for the timing and balance chains to be replaced). It wasn't slipping - even with a stage 3 map - however, upon collecting the car I was told it was a good thing to have had the clutch done, because it was worn to within half a millimetre of the rivets
