2003 model years trucks (or early 2004 model year trucks with 2003 engines) DO NOT use EBP sensor input to set turbo boost. They use what is called "inferred EBP", meaning a calculated value. This is why the VGT relearn procedure that is required after any major repair that involves turbo removal is necessary on (and EXCLUSIVELY on) 2003 model years. In a nutshell, the EBP sensor on 2003 model years, is just there to "look good".
