I'd politely suggest your buddy contact us for some tuning and component suggestions/advice. In my opinion it's really hard to suggest "an engine should run better" when there are hundreds of factors that result in quarter mile times. "setup to race pretty well" doesn't mean it has the right converter, or the best gears for his setup, etc, etc, etc,. There are 600 HP cars out there with bad converter/gear matches that couldn't spin the tires in the rain.
