I guessed it was the MAF afterall
 

Yep, after changing the MAF, my engine was still cutting power at high RPM and load. So I kept looking for other potential reason. But got tired and with all the comment about the non Bosch MAF being bad, I decide this morning to unconnect the MAF and go for a drive. Nothing, the engine run good, no cutting while shifting pass 6k. I guest the tip from Johnny Danger about MAF was not good for me. But I'm not even sure they sent me the right one after more checking on the web. I'll call them and see what can be done.

Educate me please
 

Talking to the guy at buyautoparts, he told me the car should not be running fine with the MAF unplug and it tell him its not the MAF that is in trouble.

I though that when you disconnect the MAF, the ECU cannot read air flow, so it goes to a preset fuel and ignition map and guide itself with the others sensor to be sure the engine is safe. So the engine run not at full capacity, but will run good, which is what happen this morning.

And when I connect the MAF, the engine use it, but since it seams to be broken, the ECU receive strange signal and that is why it cut power and run bad?

I'm I wrong to think that way.

What tip was that ?

Cheaper (non bosch) MAF that was working well. You had a post on that and couple of others have try it with success. Dont get me wrong, I'm not saying it was bad, just saying I might be one of the unlucky with a defect MAF.
I'm still in the process of finding out if it work or not.
