Do a search, it can be done but requires a lot of time ,money, and knowledge. The Finns are able to get 400hp+ out of 603's. The stock IP limits you to about 180ish if my memory serves me.

If you instal an EGT guage you can turn boost, and fuel up a little bit, as well as play with the ALDA. Next step is an intercooler to get any noticeable gains.
