What's interesting is that Bruce Kirkendall (PT Wiring Solutions) became a subscribing member here in May 2012 shortly after we published a great 6.5 turbo related article (that showed how to install a Holset turbo on the 6.5 along with a lot of technical data on the 6.5 and turbochargers in general). He then inquired about advertising. I responded that I'd work with him to make it work. I didn't hear from him again. I'm disappointed that he doesn't acknowledge The Diesel Page. His Holset turbo parts look just like those we discussed in an article in March 2012.
