I want to start by thanking everyone for their continued help up to this point. So, Thank you all.
Here is a brief re-cap to bring everyone up to speed and save from re-reading the whole post.
Installed T-28 turbo kit...using a base tune from Keith at ADC...began tripping CEL...using xcal2 found out they are lean codes, both banks.
Sent some data logs to Keith at ADC and based on those he was concerned about adding as much fuel as the data logs would suggest. And at that point he inquired about my fuel pressure and also stated that it should be around 40psi.
From their I searched (yeah, searched hahaha) and confirmed I should be right around 40psi. Took some pressure readings with my gauge, 30psi, had a guy a local garage also take a reading, 30psi.
After some suggestions to upgrade to the FSVT fuel pump anyway, I replaced the stocker with that and changed the fuel filter at the same time. I completely removed that screen from the bottom of the tank as well.
Took some more readings, still at 30psi, still throws lean codes.
As far as the misfire, I am assuming that it is a lean misfire as the AFR goes high at idle. However, under decent acceleration the AFR looks good in the mid 14s.
Per Todd's suggestion I will be replacing the plugs as they are cheap and hopefully the misfire is gone. But I assume that I will still have lean codes. I will be sending some new data to Keith at ADC with the focus pump and new fuel filter installed and see if he is still "concerned" about the amount of fuel the data would suggest adding.
Hopefully, it is just the ecu adjusting for the larger injectors and that some quality tuning will fix it up. I mean, I really like the fact that AFR goes to a good spot upon acceleration. Sorry for the monster post, I hope this gives the experts all they need to know. Again, I appreciate all of your help.
