Here's my current spark map. It's not dyno tuned, just based off maps I've seen. 93 octane. 95 bottom end, 99 head, and GT2871r .64ar.

 

You have a lot of resolution down low. I am running about the same timing in my midrange but at 250kpa@7000RPM i am running 19*.

 

Thanks for the feedback. I was going through different spark maps not long ago and felt like I probably had a little more room up top. I'm just a little nervous about pushing it farther without putting it on a dyno.
