Plus the car pulls out timing on it's own and after Cobb tuning, it pulls out more mid-range timing. Can that be corrected?

I'm in Dallas so Austin is no big whoop. Being I own an AccessPort, can I make further changes (frankly no more mod plans except gears, so unlikely) using the AccessPort after you tune the car?

Well the timing isn't static, and the reason you're seeing the car pull timing so much is probably because the AP is putting too much timing in and the car is hitting detonation, which makes the ECU go into a high det map and pull a bunch of timing.

As far as adjusting it via the AP after you get a real tune on it, thats not going to work as our software works as the ROM on the vehicle. You'd have to pick between one of the two softwares to run.
