He took it for a drive last night no pressure drops, he's doing it again tonight to see if anything happens
if we don't get any results of pressure drops whats our next move?

Ok, rail pressure is good (I take it you have an un-referenced FPR, I forgot already)...?
Next step: are all the injector tables correct...?
The fuel pressure we never checked at first- then there was a lean spot while cruising at around 2000rpms and 20% TPS both O2 sensors showed extreme lean and WB showed 5.4 lambda which I didn't think it could go that high. I posted a pic of the graphs in previous page. Jet pointed it out. You also recommended to double check. (Just bringing you back up to speed seeing it's been 3-4 weeks)
It's the stock injectors for the 5.3 flex fuel that came on the truck from factory. We didn't change anything.

Ok can you post a new log, or what Jetmech wants you to do...
Ok no pressure drops in fuel
Here's one log its kind of lengthy

Are those lean spots where he hit his rev limiter? Due to stall converter? Fuel shut off
I need to adjust it in the settings and couldn't confirm the correct method- do I lower the desired rpm threshold about 1000rpm? For inbetween shifts?

Just increase the MAF a little in those spots, and try to blend the surroundings, then take a log and see if it does the same.
