I still have to get the car on the dyno to get final numbers, but planning on doing that next week. The power delivery is MUCH smoother than the JB4 with the additional boost ramping up evenly rather than coming on all at once. Honestly, the JB4 was pretty much undrivable on the track. Looking at logs, AFR is also much more stable now even compared to stock.
