I did as soon as i drove off the lot in my wifes new 2007 Hyundai Sonata . she needed a good car for school and the bank wouldnt let me trade in my n/a crossfire for a used srt 6 my neg equity was to high so i just taged it onto the new car so i can start out fresh for the srt 6. yea i took a hard hit not to mention the 4k i already put into trying to put togather a turbo kit for the n/a but just like everyone els I just gave up when it came to the ems.. I lost about 7k in the trade but it would have prob taken me another 9+k to get the turbo put all the way togather.. i baught the sts turbo kit and also the liquid to air intercooler for the srt 6 also a meth injector kit. I might put the meth on the srt 6 though so atleast thats somthing.
