Hi there. My name is Chris and I live just south of you in Wichita. I just purchased my 2007 G35x this year with approx. 40K miles on it. I'm looking to start with perfomance mods and really not sure which to do first. I would really like to find a nice, used Vortech SC as my end goal is approx. 350-380whp. Have you found a tuner who can tune an AWD car? If so, where? Have you purchased any of the other HP items in your post?
