did a little bit of tuning on it.. this was just to 6800 and power has yet to peak. final run made 380hp and 313 tq with a very loose converter and this is a 2nd gear pull.

2nd gear pull supposedly lowers it an appreciable amount. Also I've seen that really loose converters can suck up 40 hp or more
