what would it take to get from where I am to 300bhp? obviously this is a jump...what mods and how much $$? I just have the stage one GIAC software upgrade currently...

 

And can it be done reliably to where the car can remain a DD?

 

no performance mod will ever truly keep your car a reliable dd, but if u were wondering and havent searched, go-apr has some nasty gt28rs setup's thatll put u round there...but ur guna pay to play. ultimately thats ur best bet, a apr stage 3 setup.
