We have a friend here who very recently received back his ecu from Irvine. That went back in his Turbo S and got dyno'ed at 495 HP. That was a +45HP beautiful day for someone here.... I wasn't there but heard that he was giggling like a little girl
+45... read correct
Not saying you'll end up with a rocket fast car but you get the idea. Like I said... even if you get +10 or 15hp more, it certainly won't be the same car
So much more responsive, cheaper in petrol, etc etc etc
Not necessarily cheap but still, not that super expansive considering /hp gains for just a small tweak lol
