E36BMW3series

Looking to tune an e36 M3 on an M50 manifold and cat-less exhaust. Running 93 and this is a weekend car, so fuel economy isn't a huge concern, although it looks like I should be able to keep fuel economy and get some additional power.
I'm a tuning noob, so I'm not exactly sure what I should be adjusting. From what I understand you add a bit of gas and adjust tuning back to avoid knock. It looks like my MAF is maxing out at around 6400 RPM and my desired redline is 7000, so I need to make guesses at the top end and add a little bit more fuel.

I adjusted the timing back across the board on my last version and that's where I've had some of my worst logs yet. Not exactly sure why moving the timing back more made it knock and tune it back further.

Do you have any suggestions on other parameters I should be adjusting? Ideally if anyone of you have a .bin file you'd like to share, I'd love to see a few things you've changed.
