I would try maybe leaning your HSN just a couple hours and come out on your LSN. I race in south Louisiana a lot (similar) elevation and temps/humidity using 30% with stock shimming and I have to run my LSN almost flush or else I will get lean bog. My HSN is around 3/4 turn in from flush.

Check your idle gap again just to be sure it is right,
Make sure car is at operating temp (around 200F is good),
richen your LSN until your idle starts to drop (indicates getting pretty rich)
put the car on the track and run it up and down the straight until it clears out at top end (should still have a good smoke trail though)
Once you reach the point where it will not get any faster on top richen up the HSN 1/2 hour
Go back to your LSN, it will still be fat but not as fat because you have restricted overall fuel flow by leaning the HSN.
Now lean the LSN until you get a steady but not crazy (controllable) takeoff and rise through the power band.
next thing to do is run a couple laps checking for a good smoke trail and performance
bring the car in and check the temps 220-280 is pretty common
now blip the throttle a few times to clear it out and then let the car idle. The idle should be steady and it should start to drop after about 20-30 seconds or so.
The only thing left to do now is fine tune your idle slighlty to where you like it and GO have fun.

This is the way I do it anyway.
