My Father-in-laws 05 F250 has no boost. I took it for a drive today and it takes along time to build RPM's. the boost gauges doesnt move until you get over 50mph. (which takes 3/4 of a mile to get up to 50mph) and when it does move it only goes to about 2 (two) PSI. I pulled the EGR valve and cleaned it. Nothing changed. Disconnected the cat converter and again, nothing changed. Checked the map sensor line it was clean.
The turbo doesnt whistle or anything. It acts like mine did when i blew a IC boot off. Just runs on all motor. All the boots are tight, none cracked or broke.
Anyone have any ideas before we take it to the stealership?
