Your delightful sarcasm aside, Sydneykid you are finally starting to get to a question I have been trying to get answered for a while. "Without changing boost, how must gain do you get with an Aftermarket ECU".
I am not claiming to be the authority, just stating what I have. My turbo's are steel wheeled with 360deg thrust bearings and the car is a GTR not GTS. It also has head porting, matched port manifolds, large exhaust, high flow filter.
