Problem with MAF sensor ?

[PulsarDet]

Here is my probleme. All my car was redonne during the winter and since then, the car won't run correctly.

Here what has been done since the winter.T3-T4 SSautocrap manifold.3" exhaust.550cc injector 300zx maf sensorredonne the piping of the intercooler.

The problem is when I start the vehicule, it's all fine without the maf and if I try to reach some rpm it's very slow, and If i plug the MAF sensor the car die's.

So far I check all the wiring and all seem to be pretty good, I do use the ca18det jdm ecu in a 1988 nissan pulsar FWD. The AFR is running at 37 psi. witch is stock factory. I also use walbro 255 ghp.

I do suppec to think's might be a bad maf or the injector size maybe is wrong. I did burn a chip for the ecu. With only the injector size and maf setting, all the rest is stock, the timing is set to 10 degres from TDC.

Any help would be realy appreciated. Spark plug are brand new by the way.
