I know that guy has a good reputation, but I promise you that no matter how good the tuner you will always have a superior tune if you tune the car yourself simply because you can put countless hours into perfection that you can't afford with an hourly rate.
I know what you mean, but I know jack all about it and when I try to read up about it makes my head spin. Plus I have no friends who care about cars and can help me tune it. So for now I'll get a decent tune from a tuner, and if I can make friends near me who know/care about tuning I'll go from there. :/

Can you tune spark without a dyno?

Only on power with boost, and that assumes you hit the knock limit before you hit mean best torque. You cant do the fuel economy part of spark tuning, and you wont get all the cells in the table.

All you need to know about AFR - https://www.miataturbo.net/attachmen...engine-afr-pdf

A very useful document.

17:1 idle just happened. I don't really advice it but you CAN run it and get marginally better fuel economy.
