got a 2006 western star with a 515 detroit in it at work, thats a little bit on the lazy side, anyone know an easy way to turn it up a little without going in and paying to have it re-rated, or spending 2000$ at pittsburg power?

 

I have the same engine in my Freightliner. You cannot turn anything up unless you do it through the computer. Odds are you would have to rechip it,
