about a yr ago I had to put my service truck on a diet because of issues. its a 12 cab chassis, used mini max. I was jus curious though now in highest settin it will make 25psi boost and before diet itd hit 30. not that it matters much cause it runs awesome but why is that? I know it freed up exhaust side but its a cab/chassis and had been told all the box tunes were pickup, is that why? it does get hot fast if you lay into it very long lol but runs great
