Well, an OFT came in the mail.
And then the BRZ got flashed. This was a lot faster and easier than I thought it would be. Torque dip not really noticeable anymore. Power delivery much more linear. Much smoother driving around town but not sure how I feel about the change in power feel on the twisties yet.
Cold starts with the HKS exhaust is pretty brutal on my neighbors so using RomRaider I edited out a lot of the cold start noise. This was easier than I thought also.

Cold starts are much better now. I'll play with the ignition timing post start again. Next time I'll zero it out and see how that sounds.
Overall, very satisfied with my purchase...
Up next... Sounds or headers... all depends on which arrives first.
