I just purchased a 2002 DTS with 55,000 miles about 8 months ago.. We have a few of the same mods Volant CAI, Eibachi springs, Corsa Exhaust. There are a few more goodies, I was just wondering if you have any pictures of your DTS i could have a look at... I'm also curious about your custom PCM, i'll keep an eye out for a response.
