I have a 2009 G8 with 430whp, I was wondering which one of your existing tuning files would be a good place to start? Specifically looking to turn down TM and get faster shifts in sport mode.

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
