Still 2 bars RICH @ idle! ..... Any ideas?

Tried all the grounding points, as well as Jeff's idea for the additional ground from the turbo exhaust stud to the front frame rail.
A/F gauge reads 2 bars rich at idle.
Mods that may relate to the situation...
30# fuel injectors (300 ohm resistor in AMM orange wire)
2.5 bar FPR
1993 900T ECU w/Speedparts fuel chip
Removed charcoal canister (?)
New AMM
New O2 Sensor
I know several people with LH2.4 that run the 30# injector/2.5 bar FPR combo and don't have any problems, so I'm thinking it is probably unrelated to the current fueling system, but maybe another sensor, etc.
Any suggestions?
Thank you!
