I would agree 100% with those dyno figures. My car has gotten faster yet which I think is due to the ECU adjusting for the increased flow. My times prove it as well.

I would find it hard to believe this car dynos at 250 HP. My Z06 dynoed at 365 stock and was around the same weight. I would think if it really is 100% MB engine with the 349 HP then it would be right at 300 stock.
