Ticking Before Boost and Engine CEL

Ticking Before Boost and Engine CEL
After boosting the car ticks/knock right bfore boost then disappears as I hit pressure (maybe drowned out by spooling turbbo?). Doesn't sound like a rod or anything that harsh, more like really loud valve tap? Any ideas.
Also I i have to idle for long, like warming the car up for a long time or waiting in a long drive thru I soon Get a 02 sensor Light. Could I be burning rich/lean? at idle?
90 dx w/zc swap
PM6 ECU with TE2.0 using Surfer's Maps (Retarded a small bit and richened up in boost maps a bit)
91 Octane Gas
14b on VX Manifold
7 psi
FMIC

Re:Ticking Before Boost and Engine CEL
I did have valve tap prior to turbo, but it's worse now, I don't think oil pressure is a problem. Have a gauge before turbo and it read 60-65 psi.
Will it hurt to lean the maps out at idle?
