what the best way to go

[gsx&gsxr]

I'm fairly new to the tuning world but thanks to good credit and way to many close calls on my gsxr im now buying a 1997 gsx and im wondering what the best way to go is the guy only had a manual boost controller and that just doesn't seem to be the way to go I have looked at lots of part and threads and i was wondering which set up would be best and most cost effective or combination of what not again i'm really new to the tuning
