Lately I have noticed that when I smash the gas my car pulls hard until I reach around 6000 RPM and then you can feel it instantly let off a little. I mean it still pulls, but you can feel it lose a little power, and it happens instantly. Could this mean it is starving for fuel? I have already installed a new fuel filter and the only mod is a cold air kit.
This is realy starting to annoy me.

Do you uys have any ideas?????
