| Re-read my post. I'm certin the Z1 system does not include a high speed valve for precise metering of water nor a microcontroller to monitor both MAF and MAP and then meter the high speed valve to get precise water delivery for both boost and airflow. Correct me if I'm wrong. I don't want to be making claims that aren't true, but I didn't see mention of any of these things in the Z1 injection system announcement. It looked to me like a system that comes on full at a preset boost set by the adjustable pressure switch.
