Many similar questions have been posted on this forum, but noting definitive. I currently have the Edge CTS and am satisfied with it, especially the gauge package. However, after my breakdown in New Mexico with the DPF clogged, I'll be deleting everything from the turbo back when the warranty is over; 2 years. I have a buyer for my CTS and want to buy a programmer now, either the Spartan or H&S, with the dpf and egr delete option before there are any more restrictions. Will someone that has one of these offer some guidance? If your were buying right now, which would you buy?
