Start leaning it until it runs clean. Any bogging is bad for it.

A lot of guys go with temperature to know how well tuned their cars are. I go by sound and behavior of the car. If it bogs down with acceleration then lean it out, no smoke then it needs to be richer. Running too lean cause overheat the engine and it will cut out and die. You can cause serious problems doing this and you will eventually have to replace it a lot sooner then if its properly tuned. Run it where you see the most performance and this is usually the right spot.

Don't instantly tune for performance, but work your way up to it through the next 4 or 5 tanks. Treat it nice now, and it will return the favor.
Lean the LSN about 1/16 of a turn. That will get you a little better idle and take off. Lean the HSN the same and that will start to improve your top end.
Every half tank or so, turn off the car, put the piston at BDC let it cool down and lean it a little more. Keep an eye on your temps.
When you've run a few tanks, you will notice that your idle is a little higher. You need to adjust the idle screw to balance out with the LSN setting.
When you're getting a good idle and a good take off, the final setting will be on your HSN for WOT. You'll need to tweak that needle from time to time to compensate for outside temps and humidity.
