I understand that.
You cant add any more timing to it or it will ping.
and the difference between a 12.5 to a 12.8 airfuel ratio is not going to make a major change in hp on that engine. 1-2 hp tops.
If you want more power, usually the best thing to do is add a cam. It is the major restriction on that engine. You can only squeze so much out of the computer/other engine parts.

Well, ideally your LTFTs would be 0 or slightly negative under partial throttle. If they are positive when you go WOT, they will offset your PE table. If your question is if your positive LTFTs are hurting your power, the answer can't be determined without a more information (wideband). No matter what your LTFTs are at WOT, your PCM is trying to hit your target WOT AFR. As long as they aren't pegged, your WOT AFR should be close. So close it wouldn't be worth more then a few HP.
