Hi, today ive installed a 'Reprogrammed fuel ecu' by superchips, i know they increase the fuel cut in them, but i was wondering if it effects the setup of my engine, the fueling etc, is there other things they could of done to it? does this ecu control the fuel pressure actuator?, i have the fuel pressure mod aswell!.

car still runs spot on as from APT, if anything it seemed it had more pull from 4k revs, but it was a bit colder outside than it has been so proberly that!
