weird fuel cut

[kandt]

i hit fuel cut at 5500 rpms at 16psi, and at 5500 rpms at 11 psi. don't know what would cause this. i'm thinking maybe its the computer or the maf. also i hooked up my pocket logger to it and it said that there were these codes. airflow signal, coolant temp sensor, and baro sensor.

3" turbo back
buschur fuel pump
greddy profec b
magnecor wires
ngk 7's
16g
hacked maf

I had a crapping out ECU with the CEL codes you posted, but most likely the fuel cut is lack of fuel to balance out your hacked MAF.

but when i logged it, the injectors were only at 54% right before i hit fuel cut.

See....if you had posted a more detailed description, I wouldn't sound so dumb right now.

Are you sure it is a coolant temp sensor error, not an air temp sensor error?

Becuase when you leave the MAS unplugged, you get those three codes...
