DYNO Sheets from L99 Tune

I'm attaching the dyno sheets from the L99 tune last night. I don't have the air/fuel up on them as the dynojet one was not working, so I had to log with my portable unit. The stock air/fuel was right on 11 to 1 and the finish tune was 13 to 1

The car really is detuned from the factory a large amount. The HP gain is one thing, but the huge Torque gain is the reason why I feel people are feeling these cars are slow.
