Protune VS AccesPort VS OpenSource
So i have owned my WRX for a year. I am looking for some more power. Here is what my car has on it right now
Turbo XS Up pipe
Turbo XS Down Pipe
Turbo XS Full Turbo Back
Turbo XS TMIC
Walbro 255 Fuelpump
With Stock TD04 turbo
It is currently flashed to Accessport Stage 2, how much would i benefit with a protune or even an opensource tune? I mean would it be worth the $$ with sufficient gains?
Also i dont even have the access port anymore it got stolen or lost somewhere between moving from ohio to michigan. So what would i have to do to reflash it without the accessport?
Opps maybe this should go in the tuning section, sorry move at will.
