These are my most recent dyno sheet and time slip. Power is 298whp and 262 ft/lbs torque, all on a fairly basic tune. More tweeking should easily break the 300whp mark. Best time at the track is 13.9 @ 97.3 mph. I was getting KR through all of 3rd gear too, so more tuning to eliminate that should result in a higher trap and slightly faster ET.
