How are you reading your air fuel ratio? Wide band O2 or stock O2 sensors?
Also, are you reading that AFR on the dyno or on the street?
10.5:1 seems really rich. How many degrees of timing are you running right now?

I'M READING AFR BY WIDE BAND O2 . ON STREET . I PUSH THE CAS FROM 20 MILE FULL THROTTLE TO 144 MILE . THE WIND BAND SHOWS 10.5.
WHAT IS THE BEST ARF NO. FOR MORE POWER AND SAFE DAILY DRIVE ?

I would lean it out a bit and it will probably work a little better for you. On the other hand, I wouldn't be too crazy about 15 at idle either.

You really should do some data logging/tuning/testing to determine what your optimum ratio/timing setup is.
I was following the previous threads about the dead motor when you got into boost, but never heard what blew on your motor. What exactly went wrong?
