We have not dynoed any stock 550i. The two 550i we have dynoed, iceman316 and SocalM5Mang, were both modded with performance products (AFE CAI and custom exhaust) that drastically reduced power. We have dynoed stock 545i that average 250 rwhp on our Dyno Dynamic which reads 10% lower than Dyno Jet

You spoke to Eloy. He gets the 545i/550i mixed up sometimes. I have been present for all the 545i and 550i dynos. A stock 550i should dyno between 275 - 280 rwhp on the Dyno Dynamics.

Look forward to meeting you and the crew!

There are a few local shops and I'd like to get a baseline.

Our Dyno Dynamics does not care whether it's auto or manual. The drivetrain loss is the same since it's a load bearing dyno. The Dyno Jet is an inertia dyno where drivetrain loss is different for auto (18% - 20%) and manual (15%).
