I had an original Crossfire coupe since 2004 and my wife traded it in for me for Father's day for a SRT-6 Convertible. I've never driven a supercharged engine before. I seem to be experiencing either driver error or some type of problem. Sometimes when I stomp on the gas at a light I have extremely sluggish acceleration. This happens sometimes at highway speeds too. I am depressing the gas pedal all the way down to engage the auto downshift button. Anyone else have this problem?
