[QUOTE="Dane, post: 1236273, member: 2494"] I had a Roush supercharger installed around May of 2016. The dealer didn't get my gauge until sometime later and then had to replace it due to an issue. What I found strange was a change in boost readings afterwards (replacement was just due to LED colors, not boost function). It seemed like my max boost went down, but I get to my max boost (reading 6 psi) pretty quickly. I have the smaller pulley, larger throttle body, injectors, plugs, and tune by JDM. Couple questions. How do you identify that upgraded/smaller pulley versus what comes normally and what belt goes with it (mine reads 6K2085-8620-AA)? What realistic max boost should I be seeing in Denver (~5,600 feet)? What should it take to achieve max boost (whatever max is)? I realize this question is a bit open ended, but I figure I'll get a couple good descriptions to compare against. I didn't notice any change in how the truck ran between the two gauges (and shouldn't), so I think one gauge wasn't right - but which one? [/QUOTE]
