I have a 2005 SRT 4 Stage 3 w/toys and 3" Corsa exhaust. I bought it new with everything on it from Dodge. The car was a monster on the street. I couldn't get down on it in from a dead stop in power level 3. I would just lite up my tires. The car was unreal until just lately. All it does is surge, in all power levels. I brought it to the Dodge people and all they could find was the fuel pump was dropping out under a load. They changed it but it didn't change anything. I want my car back to the way it was. Anyone have any ideas? Nothing has been added to the car.
