I finally got my gauges installed so I can play wiht the tune some more. From 30mph wot up to 80mph I had 25psi boost and right at the end my egt's peaked at 1400 so I let out. What do I need to do to either get more boost or how else can I lower the egts? I was told to stay under 1300. This is on a 2003 crew cab dually all stock except tune and straight piped.
