RobinHood if my calculations are correct if my baseline dyno of 268.69hp is correct I have 10.44% drivetrain loss if the engine is rated at 300hp. If I use that same loss calculation the engine should be making around 323.4hp

Otherwise standard 15% drivetrain power loss for rear wheel drive cars means BMW underrates our motor and really makes 316hp then with the JB stage 1 tune the car makes 341hp to the flywheel.

If my calculations are wrong please let me know, I'm no expert when it comes to converting power figures. All I know is my dyno shows I made more power
