Default Anyone ever figured out split BLM’s on 92-93 batchfire

Ive always had split BLM’s on my modd 93.
Ive looked everywhere for false air sources, (leaky vacuum ports), etc - to no avail.

since i cant adjust individual cylinder fuel trims, the best i can do is avg left and right bank together to ‘split the difference’ and tune that way

Anyways wanted to see if anyone has any ideas on how to correct split blm’s

Nope.

have installed headers a couple times and have always had split blm’s

even re-did the o2 wiring hArnesses - got rid of soldered extensions ( solder apparently a no-no on o2 sensor wires).

even found/installed NOS 1996 vintage ac delco heated o2’s (vs. todays made in china ac delco o2’s or bosch o2’s)

no dice
