Ok here is my issue. My car has always ran rough when cold, so I understand that concept. The problem really bad when its cold however when my car warms up I still get a lose of power feeling in pretty much all gears, thats why I don't think it could be my transmission. Again I'm not a mechanic so...
If I'm real easy with the gas it won't happen, however when I want to kick the TA in the *** and floor it 50% its sluggish. I only put premium fuel inside, and not sure where I should start trouble shooting.

I have a Diablo Tune installed, I also reinstalled the factory tune for a few days no change. My only mods are Borla Cat back and a whisper lid. No other mods. Any help you can offer is greatly appriciated.

Put a fuel pressure gauge on it and tape it to your windshield so you can see it while you're driving. Watch what it does when you get into it hard and let us know. Could also be the trans slipping.

Check the simple things like the wiring to all the sensors around the intake and throttle body area to make sure they are connected well. Check the rubber intake hose connecting the lid to the throttle body and look for tears or rips that could let air sneak in past the MAF and throw off the computer. EGR could be acting up as well or could even be a loose plug wire or plug.

Did you change the plugs or anything recently?

Turns out all my issues was caused by a dirty MAF. A $5 can of cleaner hooked me up.
