Main power limiter of a stock stage 3 is fuel. Leaning it out a little will gain you about 15hp. Next issue is redline boost, stock it falls off too much, need to hold more to redline, adds another 10hp or so. Last issue of the stock setup is the exhaust, loves to breathe, needs a bigger 02 housing and 3" Turbo back.
Do all those things, you will net around 340-350hp at the wheels.
The big dollar upgrade is the exhaust manifold, it is the biggest hinderence to getting closer to 400hp. Getting an external gate and getting a port and polish will put you around 380hp. Upgrading the wheel itself, well, thats endless depends on your choice.
Stage 3 loves meth, seen it myself. Hits like a raped ape from 3k to 5k (runs high egts stock, meth brings it down to earth).
If you are on a budget (dont know your budget $$) I would try and get a wideband and tuning device like the Diablo sport. You really cant start messing with anything until you can see your AFRs. That will allow you to lean it out a bit and up the boost too.
