Sorry for the image, looks like it got cut off. I'll have him send another.

Basically, after tuning he did three pulls with the factory tune and three with his tune. Car was pretty hot so it might have been a bit better with a cool down. Since we were trying to just look at gains, this is good enough. By the way, after cleaning up the AFR and timing there wasn't much gain from the VVT tuning. There was a pretty nice bump in the low-end torque with the TP/Comm Tq change -- it's just hard to see with the graph cutoff on the left and bottom. Remember, this is 87 octane, so we are not running as much timing as we could (about 2 degrees less than what the factory tune had, but there was a lot of KR).
