Turbo 3800 PCM Scan

Hi i got a scan posted here of my 98 gp se during limp mode.Motor is Ls6 3800 formerly N/A and am running Lucas/Delphi 42.5 lb/hr injectors. The second scan is after i reset the comp via unplugging for 4 hours. On the second scan, i got 50 psi to the rail at startup and never dropped below 45 during the entire run. Im running a Cartuning Turbo Kit with supporting Pcm. Throttle body and related sensors have 70k miles. I have a new prim o2 sensor, new map, new maf and it is clean, new fuel pressure regulator and replaced fuel filter. I get a p0171 lean code and real hard starting and random stalls. I have replaced every emmision component on the engine. I have sent my scans to my turbo manu. and he is of no help. Says everything looks fine and that my reported airflow is low. Also i was told that my o2 crosscounts are low. If someone could please analyze my scan that would be great! Iv been battling this car for over a year and didnt run into problems until i turbo'd it. I cannot find any vacuum or exhaust leaks whatsoever. Im thinking its a tune problem. Thanks in advance..

MAF sensor issue is the most common reason that i've seen for this code.

The maf im running now is off a salvaged se with 80k miles whether or not it worx is in the scan log. I cleaned it before each log.

please guys if you could analyze my tune that would be great, as this is why is spent 600 dollars on a tuner. Im mainly worried about injector flow and why my o2 crosscounts are low. Thanks in advance.

You are knocking really bad at almost no throttle.... you really need a wideband and to scan maf hz :) Send/upload your tune.

ya the car is running in limp mode. I cannot afford a wideband really broke since turbo kit and now tuner. Ill try to get another tune file up with maf htz. Thankz for your reply.
