I don't have a video of my dyno before any mods but mine made 269 hp also. Funny story, when they pulled it up on the dyno everyone noticed the pass side rear tire was low. The tech put some air in the tire and they did the 1st and 2nd passes and all was well. On the third pass just as the engine was peaking I heard a bang. I wasn't sure where it came from but was hoping it wasn't from the car. As the engine wound down and got quieter I could hear air coming out of the tire pretty fast. Come to find out there must have been a nail or screw in the tire that came loose at 150 mph.
