with water injection and raise the boost up so much as you did. Its basically like running race fuel. The only financial drawback to doing that is the hassle of buying and installing all the water injection equipment and maintaining a fluid level in the tank.... kinda goes beyond just spending $300 on an ECU upgrade. :) But combining water injection with an ECU upgrade, now there's a treat. Its looking like our 2-program EPROM switch will likely be an option for the kit as you can run more timing as well as more boost and it would be advantageous to run a program that raises the A/F a little and advances timing. = race fuel + tuning power without race fuel.
