The only way that you will achieve those times is by trading in your 2004 Limited Coupe for an SRT6 Crossfire. The Chrysler Crossfire is more of a GT car rather than a high performance car. There are no off the shelf mods for our cars, the Crossfire is not a "tuner" car. Do a search there are many threads on the subject, if you are looking for more HP be prepared to spend at a minimum $10K - $15K.
