Oooooo.......kay. That's a good one. Don't be insulted by this question then. Does it even build ANY boost? Even more importantly so being a 2003 truck, since it's the only model year that uses what's called "inferred EBP" to set turbo boost, as opposed to 2004 and newer trucks that all use EBP sensor input to set turbo boost.
