I just bought a 2005 Coupe with 35k miles on it. I drove it home from Houston to Dallas and it drove like a dream. I have the TPMS light. I saw a sticky about moving a pin on a cable under the dome light so i guess that will be my first mod. Any suggestions on other mods? A company in Houston called Eurocharged sells a tune. Has anyone tried it? Worth the money? Thanks fro any suggestions.
