Hello, I have had two PSDs and have always been very happy. Both of my trucks have been bone stock except for some minor exterior additions. My current truck is a 99.5 Dually 2wd.
I am just scratching the surface and beginning to get interested in turning up my PSD. My questions are 1. is there a good place to read about different modifications other than searching threads? 2. What mod generates the MASSIVE amount of black smoke from the exhaust? I am very interested in this. Thanks!
