I see more than 2% difference between totally stock cars so those results seem pretty similar. Without running both cars on the same dyno we can only guesstimate.
All of cobbs stage 2 2008+ vehicles that are on their dyno database are between 280 and 298 HP. none ever break 300hp with these same mods.I don't know where his claimed 315hp comes from. doesn't really matter anyway.
Your work is very solid. nice job.
