With the 4X+ tune, 3bar, downpipes, 160 Tstat you are looking at 440-450 at the motor. I ran those mods on my old 2012 and current 2013 with no issues. The tunes actually make the car more smoother to drive. Shifts are definitely more chisp. As for the PTU, that is a funny thing. Seems there are more stock running cars puking the PTU than tuned cars. I think that is due the guys with tuned cars are more maintance heavy with their car. I have well of 250 passes on my 2013 any all is good. I also don't go beating on my car daily either. So all depends on what you are planning to do with your car. Hope this helps.
