I have a smarty sr 67ME for a 2008 6.7 I have overheated my truck do to coolant system failures twice and have had to have my head gasket replaced and milled twice the smarty pushes 32psi on its lowest setting and I want something stock or like the h&s xrt that only runs like 28 then cuts back to 22ish I have the egr dpf delete kit so I need something that has the tuning for that. I just want to get out of the hot rodding game its to expensive!!
