Stevenson East has been servicing my 03 DC Taco for a while, and as I have been unimpressed with the SC on it, I paid for the 7th injector to be added. Unfortunately, I still don't think it's running right. I expect SO much more, but don't have anything to compare it to. So, if you have a DC or Xcab with SC and AT, AND you are in the Denver area, PM me. I would like to know who you are getting good service from. This was the first 7th their top guy had ever done, so I am hoping that someone has some help!
