Is the Emission harness from the NA or a turbo harness was used? Not the Engine harness, but the "Emission harness."

 

All wiring on the car is stock to the car, which is a n/a gxl 87.

 

I have checked ecu, maf, tps, pressure sensor, all 4 injectors, crank angle sensor, fuel pressure, vacuum leaks, fuel system, coil lacks, alternator, and starter.

What am i missing?

 

What problem are you trying to get help with? The 4 psi boost cut?

 

^yes^. It also bogs here and there and is also hard to get started after warmed up. I have a fcd on so boost shouldnt be cutting at 4 lbs. Im getting fed up with this build and want the problems fixed before i got nuts. Its actually starting to affect my personal life.
