M1000 A/F #'s?

[Sparx]

I'm trying to make sure I got my sled running safe and have the A/F gauge all set up now with my SLP single pipe and BDX intake setup. It appears to be running between 12.5-13 on hard pulls, but is everywhere when off and off the throttle making it hard to understand what is going on. Sled runs great with the new BD Box suggestions off the SLP website for the '07-08 settings. My sled is a 2007 M1000 with the '08 reflash and really runs good and hard with 65gram adjustable cutler weights set around 68grams each pulling around 7800rpm. What should I look for in numbers and is it okay if it reads a high lean number when off the throttle? I have the sensor located in the silencer inlet of the SLP can. Used to EGT's and not sure what is my target numbers across the board from idle on up???

The sensor is not correct at low rpm`s because it does not get enough flow to read accurate. High numbers at low rpm`s is ok/common. I would keep it below 13 at wot.
