Message Just put a new turbo kit on a new built engine, got a question about the ECU. Z1 sent me an upgrade EPROM to stick in my ECU, should it be already tuned and ready to be driven on w/ out tuning or should this new EPROM have to be tuned for maximum performance? I've heard that people making universal EPROM's most likely run them on the conservative side so as to not run a car to lean as each car is diff. Thx for the input.
