extra boost 89 200 Turbo?

[TMFINN@ccmail.monsanto.com]

     is there an inexpensive modification i can do to the wastegate spring
     to boost pressure on a 89 200 turbo, or does the fuel mapping chip
     need to be upgraded also?  right now i think the car delivers 162 hp
     at 5500 rpm.  i've read where this can be increased to approximately
     220 hp?  if anyone has done this, or knows some info, please let me
     know, i need more passing power (one hour commute to work).
