Make sure the MAF sensor is installed facing the correct direction and is connected.

Yes, but I can run with the car, but when it's time to go in boost, the redline come in. I can go slowly at hi rpm, but when the turbo spool, the redline in comming. You know what I mean ?

Usually that is a MAF sensor error. What year is the car? Did you already install the Unichip or get the ECU back from flashing?

I got the unichip, it's on the car right now. Did you think that the unichip can have an issue or error ?

It's possible. Can you hook up an OBD2 monitor and see what the MAF voltage is at idle, mild load, and under boost?

Wait, the car is an 03 with a Unichip? That's not right. The Unichip only works on the 04-06 Spec. The 02-03 needs an ECU relfash as the Unichip wont work. That would explain why you are seeing a MAF sensor error as the Unichip isn't able to clamp the MAF voltage at below 4.5V
