After talking with the guys at MSD, I played with the fuel accel setting. Ended up with 80% from 0-3000 rpm and back up to 100% at 6000 rpm. Really helped throttle response.Yep, a little rich at the bottom. Made some minor adjustments but that was a very good starting point.
I think I need to adjust the fuel accel at the bottom end. Not sure what to do there, I guess I need to read up on it more.
Also went up on the fuel across the board at 0% throttle and it got rid of the flame out the pipe on decel.
