SLK/R171: HP increases
High Flow Filters (K&N)
Exhaust (Eisenmann, Remus, Supersprint)
Those are the more basic upgrades which are relatively simple. You could look into Kleemann for forced induction tuning, but it would be very cost ineffective to the point where a 55 would be a wiser choice.
Good luck and have fun.
Brabus
Carlsson
Lorinser
RENNtech
Those are the big names.
www.euroteckmotorsports.com for more.
Brabus, RennTech, Kleemann, Carlsson are all MB exclusive tuners, and the ones I mentioned also offer stellar products, but for a variety of cars.
Have fun.
