Well I wouldn't of wasted money on a BBK TB for starters. And on 93 octane the factory tune is pretty optimized from GM. I have seen gains of around 9-10whp from a tune alone. I would suggest doing a little bit of research before you start buying parts.
Ported Stock IM/TB - 17whp
Rotofab dry- 8-10whp
Cat delete pipes- 10-15whp or Cat less Longtube Headers 25whp
E85 flex fuel tune - 25whp
