Default Link A/F Is this as good as it gets?

Pretty much title. Is the below picture as good as it gets with a link ecu? or is it possible to get it closer to the target with more fine tuning / manual smoothing. Any way to fix the lean tip in? the enrichments dont help as they add the extra fuel too late. Or does it not matter being a bit lean on tipin? i would rather not be .

Added second pic i found - a dyno tuned link that i think shows its possible to get some decently accurate fueling. still really open to comments.

Is that autotuning? I tuned my MiataLINK with the FM software and the OE LinkElectro software manually and had no problems doing what was needed. Basically went like this: Log, tune, load, store and repeat.

if you haven't done any manual tuning, that's the problem. the autotune can only get you so close. also, if it's getting lean on tip in but it's near the point of full boost, then you fix that by adding fuel on the zf table. on my car i had to add fuel from 3500-4500rpm.

Thanks guys, ill get on it. How long does it take to get to a point where your comfortable with the tune? ive been working on it on and off but never really get a big block of time. I figure 3-4 hours should get it pretty nailed
