As far as the tune, what we were mainly able to do is clean the A/F up which made the car safe. The timing we demanded was kicked back by the ECU and I feel higher octane fuel than our California 91 garbage will help the car perform better!
So, I guess that confirms that timing advance via "tune" still isn't possible - just fuel maps?

Given VVEL, and how it works, it makes sense that they'd not want anyone tweaking timing, you get a valve too far out there where it shouldn't be, and it'll get bent....
