Default Dyno Video - 620HP on Map2? - 06-15-2022, 12:10 PM

I think this dyno is a bit optimistic.
His baseline with just a forward facing intake was 489RWHP.
Map 2 with "some duty cycle changes", 3.5 bar TMaps was 621RWHP.

2016 550i. Does he have a factory freak or is that dyno way off?

Seriously doubt it. I don't think the TUs turbos can support that. Its pretty close to what Pure is seeing with their Stage 1's.

I'm personally less interested in the random number generator (dyno) discussions these days. They are only good for a before and after delta on the same day really. If you want to know if your car is fast run a couple of 60-130 sprints with a dragy.
