Sorry to keep making threads but I just cannot figure this out.

idle rpm, AFR, timing, load, throttle are all hunting/oscillating. No CEL's, no soft codes. O2's are brand new. Throttle adaptation is fresh.

I've tried flattening in the Idle areas: KFMIRL, KFZW/2, KFZWOP/2. I've raised KFMRES/K, I've dropped and zero'ed TEMIN/VA. My TVUB is:

8-1.619
10-1.459
14-.651
16-.443

KRKTE- .06149400

Trims are +-.02%

Injectors are EV14 550's

Does anyone know the maps related to Power steering/torque reserves for that or the whole module? Specifically the power steering switch

I looked back into my data library and found that the issue started after i rebuilt my engine. After the build i put the oem injectors back, oem maf, oem turbo. I’m not sure what that tells me about the issue really...

O-Rings of the injectors are old and stiff. There is a leak and possibly.

I suggest running a stock file, with only krkte and tvub adjusted for your injectors and see if you still have the issue.
