I've not got any experience of the superchips map, but most stage one maps ( i have a revo one) will give about 210bhp and more importantly a lot more torque. That is the bonus of having a turbocharged car, big performance increases compared to N/A cars when it comes to remaps. It makes a huge difference to the feel and performance of the 180 models and is pretty much a no brainer.
The only downsides are you will need to tell your insurer to keep things legal, and obviously it puts a bit more strain on the (almost 20 yr old) turbo and engine. That being said, the engines are able to handle roughly 300bhp without needing rods and the turbos are also pretty reliable if you use a good quality fully synthetic oil and let the engine warm up and cool down properly before and after booting it.
I have had my stage 1 map for a few years now without any issues.
