Hello guys. I have a 2007 mazda 3 i that I upgraded. Installed a turbo, intercooler, air and fuel wideband, bigger injectors and exhaust. My problem is that everytime the revs go hi enough to get the boost going, the throttle cuts and halh the time my engine dies. Fuel and air has been adjusted in many different ways but the problem still there. Talked to some shops and some say is my ECU, some say is the fuel and air settings, but no one can tell me what to do to fix the problem. If anyone here done this same upgrade or knoe=w of some one that has an answer please let me know. thanks for all the help
