Great numbers for only 91. Can you maybe provide a log?

Thanks. The only "bad" thing I can see is a throttle closure and some timing corrections between around 3,800 until 4,800 rpm. Seems like a little bit too much boost in the beginning. But except for that pretty nice values considerung 91 oct only.

Normal, you're not supposed to start that low rpm at high gear anyways.

What's important is the results after 5k rpm.

Here's a multiple gear pull example.

A few corrections but nothing too serious, mostly heat related and 91.

But you're still seeing positive timing so it's not a bad map to run.
