If you still have the soft rev limiter in use, it will retard the ignition at 9200 RPM.
If you bypass the soft rev limiter, it will allow full ignition advance to the 10200 hard rev limit.
This is usually good for an extra 4 to 5 HP due to the extra 1000 RPM ceiling.
Although this is at the extreme upper end of the rev range.
In town, mid-to-upper range is the order of the day.
I see you're also in Florence, KY.
And while you're near the Ohio river, if you travel south up into the mountains, the elevation can detract HP as well.
For cars, it's usually 1 HP for every 1000' elevation.
