11.0:1 during full boost. Some people richen it a little at max torque, and gradually lean it out a little towards redline.

Look at the log Phil posted for his Element Hydra in the Element Hydra Tuning thread. Seems like leaning out in upper RPM is desirable with timing adjustment.

That sounds pretty normal to me. I've run anywhere from 10.2 to 1 to 11.5 to 1 on 93 octane and my stage 4 setup.
