Porting the wastegate doesn't increase boost. Not porting it with a free-flowing exhaust and FCD/Rtek/standalone would cause large boost spikes in the mid-range (3500-5000 RPM). He will still need a controller of some sort to bring the boost level above what the wastegate spring allows (6 psi). If money is an issue, do it on the cheap: http://www.gusmahon.org/html/boostcontrol.htm. I built a similar MBC for my car, and it has been very effective. The only thing I changed was I added a check valve instead of drilling a tiny hole to vent pressure after letting off the throttle.
