I have a 2004 GMC 2500HD Duramax diesel and I am in the process of adding a better air intake and exhaust system as our new heartland is bigger and heavier than what I had before. I was curious as to what additional gauges I should add, such as exahust temp guage. The truck has the stock transmission gauge, is that ok or should I add another transmission gauge, boost gauge, etc. Any help, info and education would be great. Thanks
