Oh ok cool, my flatmate has a dynopac 4 hub setup, seems to work pretty well. You might want to look at getting something to detect knock if they dont have any tuning gear.
Yeah sorry I just dont think its as good. You dont have the control you get when you go aftermarket, unless you change your chip and burn a new one. Some shops do this, not that I have seen on the 1UZ yet though.
My thoughts on adjustable and non-stock fuel regulators. Why bother at all, its just for show. Get properly sized injectors and an ECU to control fuel... and youre done.
