Car was at operating temps before the logs were run. 4X runs on the email tune to get a baseline and used the best repeatable run. Rhino (GPI) did a great job and was very professional. VVT tables were properly set to get the most HP/Tq at the earliest rpm. 
This isn't posted to bash remote tuning, but for many to understand the reasoning why some people say to dyno tune whenever possible. IMO, you can't see the fine tuning needed for getting the most from your car with just logs. You can get close if you have a GOOD tuner that pays close attention to the logs but there's always a little left on the table.

Was the first tune possibly very lean and experiencing knock retard? What was commanded AFR vs the actual AFR the car was getting?
