Why do you think you are running lean?
Looking at your tune, your PE table is set to 1.125 across the board which gives you a AFR around 13.1. Many people are getting more power at 1.16 or 1.17.
Your Spark Table seems a bit modest with only 20* below 5200 RPM.
Your VE table isn't as smooth as I would like, but seems OK.
Nothing really jumps out at me.
Again, why do you think you are running lean?

It would help if you posted a log file - include both the .hpl and .cfg files.
Besides the typical RPM, TPS, MAP, MAF, Advance and Knock, also include Cylinder Airmass.
"Torque Delivered" is also interesting, but closely related to Cylinder Airmass.
The Airmass tell us what row in the Advance tables are relevant and also a general idea of how much power you are making.
Finally, if you can include the Wideband in the log, that would be great too.
I have ideas of how to tune for timing without a dyno, but to be safe I would rather have the experts here give suggestions and methods. IMHO, 24* from 2400 RPM and up should be safe and still conservative. You definitely want to log any Knock as that indicates you have too much advance for your setup.
Finally I would suggest increasing the PE table to 1.16 or 1.17. It takes a dyno to optimize it at different RPMs, but those values are a good starting point.
Again, I'm not an expert at this and I hope others confirm or correct me.
