The trim on doors and sides are extremely easy. The rest are bit more difficult, and hardest to remove is the one on the ash tray cover. This DIY instruction guide was very helpful for me:

The vent gauge reads your vacuum and boost pressure (in PSI). It is really fun to see how hard you are working your turbos when you have a tune like the JB4 (which I had in my car).
