Ah ok these are much much clearer answers.

It (the tune) would not be worth it unless I did some more work to the car (intercooler, turbo, etc) which I am not planning anytime soon, im having enough fun getting used to the car's current power/torque after just an exhaust and tune a year and a bit ago


Thanks Kato, Nauli and JDM_STYLE, much appreciated
