Cam Coole at Lightspeed Innovations in Red Deer just purchased the tuner license for Uprev and wants to work with the Nissan guys, so he recently set up an introductory "group" discount for the first 5 or 6 people.
Check out this thread for more info:
Anyone Interested in "uprev" in Alberta?
Cam's tuned 370's before using Cobb, but Cobb no longer supports 2010+ Z's. I'll be getting mine dyno tuned (Uprev) by Cam in a couple of weeks.
