i agree there just doesn't seem to be any cost effective way of adding power to these cars and they are a bit peppy when compared to economy cars. anybody that has had a car with a little bit of get up and go can agree these crossfires (non-srt6) are turds. they may have a 140 mph top speed, but they just don't pull hard enough. i'm not bashing, i love my car, but fact is i would love to have more power as i've tasted it in other cars that didn't look as fast as my xfire does.
