I don't know what boost levels the load corresponds, but I would say the timing is too high from about 100-140 load roughly and from 5000 rpm and up roughly.
Using both my Jackal maps and my Mazdaspeed maps for a rough reference, I would lower the timing in those areas a few degrees. That is when the engine is under the most stress and the most load is on the rods, bearings etc. this is where cylinder pressures are really high and where boost normall hits really hard.
This is based on pump gas however. If you are on race fuel, that might be really nice. Also, if the timing maps on this don't correspond with other tuning systems, sorry, I can't help in that case.
The AFR however, does look screwy from 120-200 load from about 4000rpm and up. There is a serious lean hole here it appears to me. It is much richer before that. Possibly too rich for optimal torque but safe enough. Mid 12s are too lean at higher loads and rpm. But again, if you are on race fuel, different story.
Also, I would work for a nicer transition from the mid 14's to 12's. There is one thin line of 13's in there seperating idle from boost mapping. yes, the car will run, but it won't be smooth, it won't make optimal torque or power and it will get shitty mileage needlessly. Plus it may hesitate when it gets that huge dump of fuel before it needs it. Or if it needs it there, it will be too lean just before the map richens up.
Again tho without knowing if the maps are the same as what I am used to, I may be just talking out my butt.
Oh and even if they are purely race fuel maps, the AFRs shouldn't be that rich(mid 10s) down so low in the load table, and then just jump up so quickly. As well, the timing maps should steadily increase. The engine needs more timing as the rpm increases not the other way around. Both in just the simple physics of how the piston speed increases with rpm and with the fact that detonation is much more likely at mid range rpm than higher rpm.
