I dont think the MAF is causing that problem. Your trans is shifting at a higher RPM regardless of what the tach says. In most cases, the tach is just too slow to respond to the higher RPMS. I would bet money that if you connect a scanner and take it for a drive, you would see that you are shifting at a higher RPM than the tach says... I don't know why you have a 'dent' in your MAF. I wouldnt worry about it too much unless you start going crazy with mods.... (not intake/exhaust/tune) more like SC/Turbo or Nitrous.
