That just clears the codes. Normally driving it long enough will move the adaptations to where they need to be, but sometimes it's a good idea to reset them and have it start learning all over again, especially if there were codes that may have moved the adaptations in a bad direction.
As for if it's too lean I don't know enough to say for certain. Maybe someone that knows for certain can chime in.
The thing with flashing back to the previous tune, is that since you also changed the hardware you won't know if it also will run lean or not. You do have more air coming in with the less restrictive headers.
If anything maybe I'd flash back to stock as that might be a more conservative tune. In the long term you should work with evolve, I'm currently doing that process (adjusting my tune) with Sal.
