I have a 97 6.5 TD and had all of the symptoms of a bad PMD. After researching solutions I ordered the FSD Heat sync and installed it. Now my truck runs smoothly. This is a great product and it perfoms well and installs easily as advertised. Thanks SS...

Had issues with stalling and starting after the stall. Ordered the FSD for SS diesel Supply after reading the testimonials. I have driven for approx 50 miles with no stalling. Seems to idle and run much better now. Thanks Guys!!
