Damn, that was way out of tune to pick up that much Hp/Tq with a tune only. I imagine the old butt-o-meter felt that difference.

Glad you posted before and after. It happens that a car comes from factory way out on the power curve, both high and low. This shows something esp. since it was done at a reputable shop and back to back runs to improve it. Looks good now!!

Do you have the air-fuel graphs?

No, but the AFR was 10.0 (or lower, we don't know cuz the scale doesn't go lower than that) for the baseline and they leaned it out to around 12.8.

So the way I like to see it is... my car had a screwed up tune from the factory. They fixed the tune which put me around normal LS3 numbers, then gained 5 rwhp from adding some timing.

Thanks for posting and taking the time to explain your concerns. I do agree that you were right - we would have screamed foul!
