just moved up here decided to dyno her for the first time. map 2 for the first 2 runs and map 5 and the last. 15-18 psi. 91 octane and some octane booster. very happy with with results as it was very unexpected. the car is auto with steptronic so about 20% drivetrain loss

65 degrees and humidity 11%

Torque at MAC dyno always reads very high, but HP should be pretty close. Were you able to get a baseline at all?

Jesus. Those torque numbers are insane!

You should have let map 5 adapt with some pulls on the way to the dyno, then switched to map 2 for more accurate results

Great numbers regardless!

MAC uses 25% correction factor on their dyno and that is only relevant for NA cars at our elevation so those numbers are skewed. My 335 put down very similar numbers so I speak from some experience there. Did you do a stock dyno to get the delta? That is the best way to see the real improvement over stock at MAC.
