ReTuning necessary?

I have all breather mods with no tune and dyno'd pretty high for a 7AT.

The tune gives you more than just power though

Do you know what AFR you are running at WOT from 6k and up. I'd love to know how lean it gets if you've monitored that on a stock tune with multiple breather mods.
