id say if you went cobb stage 2(what i have) you can pull consistant 13.5-13.9 at or close to 100mph. All it is a turboback,uppipe and cobb Accessport(basically a handheld ecu reflasher).
Its what I have on my car, very little turbo lag and it drives like stock except more power.
Nasioc doesnt take to these types of questions to well...they can be a bit hmm harsh.
