Just had it done today and I thought I would share the graphs etc. Took a little under 2 hours. Pulls way harder between 2-3k rpm where those dead spots were.

Gains were 22.9hp/18.8tq on this dyno. It's a hydraulic dyno and i'm not too sure how much that changes the numbers compared to a roller dyno.
Red is baseline.
