Help...this is simple..right?

Hi All, Help, I need some direction!

930 engine, CIS with Leask WUR, Rebuilt fuel distributor, twin plug with Electromotive ignition
Wide band oxygen sensor and EGT just installed. Recently rebuilt engine

Starts and idles just fine...AFR @ 14, EGT @ 700
Accelerates just fine
Steady state 60 mph 4th gear on interstate AFR between 15.5-16 EGT temp to 1450..way lean
Go to full boost...AFR to 11.5-12 and EGT drops back to 1250-1300, i think just right

I'll tell you, it is strange to get into boost to lower EGT.

So, what is the adjustment to get more fuel at very little throttle? O2 sensor is hooked up.
Thanks, Jim
