It's been a while since I've tinkered with my calibration file as I had twin girls over two years ago so family definitely parked the RX7 for a while.
But now that I have some time again I've been looking at my map and it has a huge incline between boost and vacuum and I've never seen such a map like mine. I don't know if it is a bad engine/turbo combo or just a bad tune. I'm running boost comp table as well. I'm uploading it here to see if anyone has some insight.

Half bridge with a "race" exhaust port
single turbo, I don't remember the size/type other than 60-1. I'll get the exhaust AR if needed.
550/1600 injectors.

 

I havent looked at the map yet but do you have any logs? Fuel map should have a consistent shape to them but that doesnt mean it has to be that way every time.

I did post an image of the fuel map as well, the image tags didn't embed the image, but you can click on the link in my post. Haven't done any logging, perhaps I will tonight.

 

Did a quick log, a couple of loaded runs in there. I'm not sure every parameter you need is logged, as I don't remember how to turn them on, plus it was hot and my AC doesn't work right now.
