I would stick with the 15lbs or so limit on boost, I wouldn't bother taking the pump apart to shim the gov at this performance level however. Turn in the main fuel screw, also grind the fuel pin and adjust the star wheel down in the AFC housing slightly for a little more low speed fueling. You also need to look at the condition of your turbo, and check for intake and exhaust leaks. The stock turbo is tiny (.36 A/R exhaust housing) and should spool instantly almost. If your not making boost untill 3k rpms, somthing is leaking boost out, exhaust is leaking out before it gets to the turbo, or your turbo's compressor impeller is junk. The stock turbo should be spooling or starting to make boost by 1500 to 1800 rpm and easily make full stock boost by around 2000 rpm. My big T3/T4 can make 20lbs of boost at 2500 rpm, and full boost by 3000, and this is with a much larger stange III .63 A/R housing. For you to have that lazy of a spool up something isn't right, I would look into that first.
