Before going to the dyno I had boost numbers twice as much at 4000rpms than the day of according to Haltech logs. It was a combo of advanced cam gears and retarded ignition to spool. It was a beast. I put everything back to start with so there was a known base settings for dyno day. Unfortunately I ran out of time....
I'm not saying these turbos will spool with your car but I know it was way better down low with this setup in a different tuning state.
