closed loop idle BLM 128, Integrator 147+ very lean?
too lean? O2 values are between 100-200 mv also. Timing will not advance past 25 degrees with slight load in neutral.
A ZZ4 cam, extruded MAF TPI with TF 23 heads. 19lb injectors. This truck can idle but any load (in gear only) causes some backfiring. I know that the fuel delivery with a stock 305 chip and 19lb injectors is not nearly enough fuel delivery.
Base timing is set at 8 degrees and idle at 750 (very smooth idle). Any input?

Base timing at 8 is fine.
