I have a 05 baja turbo, if you are looking for 300-325hp you don't need to swap ecu's or even do that much work. A downpipe, sti intercooler, catless up-pipe and used vf48 or 16G will get you 300+ hp. You can spend $150 for an ecu plus 650 for a accessport or just use romraider. I tuned mine on romraider and had no problems.

The baja has the same motor as the 04-07 sti, just detuned with a td04 running 11lbs of boost. Once you get to 330-350 you should go with larger injectors, 740s or 850 are fine and maybe a fuel pump.
