My car has started bogging between these RPMS. I have not changed any thing and no lights are on my dash. It runs fine at any other RPMS. I have a AEM intake and a dynomax exhaust. I have had the car for 2 years now and this problem has just started. Any help would be appreciated.
Thanks Josh

Has the weather changed dramatically? Humidity?
SVT's are notoriously effected in this respect...

when does this happen in your drive, when the car has sat overnight and then turned on in the morning and drove before it heats up properly it will bog, mine does it everyday. it goes away after about a minute and my car is heated up.

change your oil.

When's the last time you did a tune up?
Plugs, plug wires, fuel filter, and air filter (cleaned and re-oiled in your case).

Is that AEM an SRI (short ram intake) or a CAI (cold air intake).
If SRI, hot/humid weather will cause exactly what you're describing.
