Im happy with stock boost. Im more after fuel efficiency, holding the boost longer and spooling faster. I think I read somewhere that the wastegate actuator is adjustable, I might adjust it ever so slightly for enough of an increase to not freak out the computer.

Oh I also want loud noises and cool turbo noises. If the car is going to look 100% stock, it might as well sound other wise. Ever since I took my last turbo apart and my wifes evo needed serious repairs, I've just not felt the same.
