I have a 08 lmm Did an egr and particulate filter delete, and a injector pump , with a lift pump. Now I have a P0101, reduced power message. Saw that my airflow Ratio is .3:1 I have smoke the system for any air leaks can't find any thing wrong. Is there anything I can try or is it a tune Issue.
P0101 is an mass airflow performance message. Meaning it is out of range for what is expected.
What is your g/s at idle?

At idle cold I have
MAP 94 kpa
MAF 35 g/s
BARO 95 kpa
MAF 3500 Hz
commanded A/F Ratio .3:1
Can anyone help? I'm not to familiar with programmers / tunes. If I just buy something from efilive will it fix it? A buddy of mine has hp tuners and cleared the codes out and try to change a few things but can't get it to come out of reduced power then set a p0101.
