Closed Loop Chasing AFR

[Turb0_Joe]

I have a problem with my Closed Loop chasing AFR. Setup is a 6.0L turbo injectors are Holley 160 lb/hr low impedance, Dominator ECU. Car runs great if you roll off throttle 2-3% and hold it, the car goes pig rich into 10s. It will cruise perfect perform perfect until you just ever so slightly roll off throttle, 13% TPS and roll to 10% Closed Loop on or off it does the same thing. Just had injectors cleaned still does the same thing.

Have you data logged this and compared your readings to what is commanded on the "Target Air/Fuel Table"
There is a bunch of guys way smarter than me on here, and I know they'll need more info than just the symptom. Can you post your config file and data log for these guys to look at?
