I need help on my 350z which I acquired last May month. It was broken before. It's a 2003. I have a problem when I want to make race because it blocks a few times 4000rpm. I went to Nissan and they found nothing abnormal. I thought a MAF problem then I changed it but the problem has diminished but it remains. When there is humidity, it's worse. I have an Injen intake and a pre-filter which has fallen as the problem. When I weigh it blocks a 4000rpm so I degrades in 3 and I deliver it in 4 to unlock it and it works sometimes but not always.

I am not at all what's the problem

sorry for my english
