Looks good, only one change makes it better, clear side indicators.

A good service does wonders for these engines, I do oil & filter changes on mine every 6k. It actually costs very little to do, 10W40 semi-synthetic is relatively cheap and with these diesel engines, as long as its 10W40 semi, then it'll be fine with it so there's no need for buying amazing super-expensive oil. If you work the turbo hard I definitely recommend using these shorter servicing intervals.
Other than that, make sure your airbox & lid are properly secured, normally the bolts rust out and you get a leak between the box and the lid. Check the condition of your radiator especially the bottom corners, they are known to rust. Has the car ever had a clutch that you know of? It looks to be a Veloce so is a little lower than normal, watch out for speedbumps if you hit one a little fast you are liable to crack the sump, they sit quite lowin the engine bay. Check your boot seal, if its looking a little ratty I would change it, quite a lot of 156 saloons get wet boots these days. Make sure all your bulbs are working (check manually by looking at them), and then check your rev counter to make sure the bulb failure warning light is out - the light staying on is a common fault.
When driving, try not to use full throttle in 4th or 5th below about 2,000-2,500 rpm as these engines are proper torquey and you will wear the transmission out quickly this way. The 5-pot loves to rev so if you need to shift, drop a cog before booting it. If it feels lethargic over 3,000revs, it would be wise to pull off the top boost hose and have a look inside the throttle body - its probably full of oily soot by now, its not too hard to take off the throttle body and give the inside of the inlet manifold a clean out. The oil comes from the turbo - not much you can do about that, but the soot comes from the EGR valve which is located on the back of the inlet manifold. I've capped mine off and it made a noticeable improvement to how it drives. And I'm happy not to be sooting up my inlet manifold anymore.
As for the remap, you will have much more power & torque, a more flexible engine, and if driven in the same manner as before, a few more miles per gallon. However, you need to change the oil more frequently and you'll probably kill off the clutch and flywheel if they are anything more than a few years old..
Best of luck with it - sounds like a good car.
