It depends on what you want to do for software, as Jriggs has said your ECU has an eprom and their are several chips available on the market so it really depends on who you like or fits your needs. As for like standalone tuning Alpha is probably the best tuner in tampa for your standalone needs. And for F/I we have done several projects from an AA twinscrew M3 to a GT35R Turbo M3. If your really serious about going with boost I would recomend either Technique if you want to tune the stock ECU or AEM for a standalone. Good luck!
