I think Japan (just like they do in their own country) are purposely leaving this car down on power. 10 psi is probably just waking up the engine. WIth a boost controller and bigger exhaust (not sure how big it is already) what makes you think this thing won't handle 20psi daily driven? That would put this car's power where? ~8ish +???? The looks of the car blow though IMO, but I say that about every new car that comes out. We'll get used to it.
