Fuel pressure ok? (stab in the dark)
Might need a scanner/datalogger to see what all your sensors read...

It’s steady at 43 which I see is normal for the LMG. Where can I see what numbers are normal for the other sensors? I think everything is normal other than the richness. I have an innova 5610 scanner. It reads everything.

What are the Long Term Fuel Trims now?

Also, I forget the term but what is the injector pulse width for each bank?

Have you considered putting the old injectors back in and have a look?

O2 sensors showing good activity? Can't tell you what is normal for all sensors, but I can look at my logs if you want to compare something specific, let me know.

as far as MAF, at idle about .9lb/min,
max recorded I see at full throttle, 4500rpm about 85mph..27lb/min
cruising at 75-80mph, 35% throttle the MAF averages around 5 or 6lb/min..
Doesn't seem to go past 10lb/min unless I'm over 35% throttle..

Have you disconnected battery to reset? disturbed any ground wires?
Might omit the disabler device until it's sorted
my LTFT range from about 7% to -10%..

When I reset the fuel trims they work their way up to -18.8. Then they go to -30.5. I’m going to run it today and get some figures.

What typically causes the alcohol content to be off? I never get E85 and my readings are frequently in the 10% range..

I think there may have been an updated calibration that was intended to correct that, but I'm not really sure.
