Losing torque around 2,500< rpm

Hi, I drive a 2000 prelude base and I have a little problem. When I just started the car it tend to lose torque around 2,500 RPM and higher and the motor sound like choking (as if not enough air is going through) then around 4,000 rpm it kick back and run normally until I shift. After 1 minute the problem stops and I don't know what it could be so if anyone could help I would be very thankfull. Also I have a AEM air intake with a skunk2 megapower exhaust (not sure of the size).

vtec wont engage when the motor isnt up to running temp.... also, theese motors arent built to make power down low.

Re: Losing torque around 2,500< rpm

Scuse me I think I didn't express myself correctly I am not talking about performance here. The motor is not torquing at all I press the gas pedal but nothing happens until it kick back and regain all his power. Nothing to do with the vtec or performance. I also noticed that it happens when I drove the car (no problem) and shortly after shutting it down and driving it again the problem appears.

Is your Prelude a 5spd or automatic? I have a auto and low end power kinda sucks but high end is pretty good.

Same here, after 2 or 3 times it stops.
