There's all the stuff like Edge, Hypertech... for the Chevy, Dodge and Ford. My question is does anybody know of any companies or Diesel Shops that up the horsepower for Freightliners. Is there anything available like bigger turbos, injectors... for those of us ( that would be mehttp://www.dieselplace.com/forum/smileys/Big Smile.gif) who can't leave things alone. Thanks,http://www.dieselplace.com/forum/smileys/Evil Smile.gif Dave

Check out tstproducts.com I think they sell a box made by pittsburg power, it is only for certain engines.
