People put a lot of hard work and/or money into making maps for their car. Most don't take well to just giving them away. As well, I would never trust a map for one car to work in my car. I might use it as a starting point and do VERY conservative runs and work from there. But I wouldn't really use someone elses map.
Shoot for AFRs from 10.5 or more, but probably not higher than 10.8. 10.5:1 is pretty conservative. Those are good targes for 91 octane. Generally when tuning a delta of 0.2% MAF voltage from yoru fuelmap will changes AFR by aound 0.1. There's no hard and fast linear relationship, but its a safe way to estimate the changes you need to to.
