MAF problem

[iron bird]

ok so ive tried 3 different mafs and get the same problem, the car runs great with the maf unplugged then when its plugged in it wont rev pas 3,000 rpm stock boost gauge reads 14psi. im lost and dont know where else to look...

tps- good, new 02 sensor, boost leaks check and checked again nothing, new pcv valve, new temp sensor, new egr block off, what could cause me to run so rich with the maf plugged or thats what i believe is happening.

is you mods list up to date? the only mod you have is a gm maf and maft?

ive tried 2 stock mafs and the gm maf and get the same problem, only other upgrade is a 3" turbo back exhaust

do you have a logger?

im trying to my logger cable to work...but ive ruled out the maf something is causing a lean condition i set the maft to 540 injectors and the car runs great
