Oil Change now no boost?

Oil Change now no boost?
So, today I changed my oil and i switched from Rotella 15w40 to Rotella 10w30. The truck ran amazing driving to town (roughly 18 miles) the oil was around 188 and coolant at 184. 3psi of boost at 65 and roughly 17 mpg. On the way home however, i noticed the truck had a slight loss of power but not much. After realizing that I noticed i was only pushing 1psi of boost, I got on it a bit and still only 1psi. I can hear the turbo still, but when im accelerating i just hear the motor and no turbo until im cruising, or decelerating. Still managed 16mpg... Any ideas? Thanks in advance everyone!

Check your CAC boots, especially the 45* coming off the turbo. They tend to rip, even under the clamp where you can't see.
Not sure what year you have,if its a 05 with plastic CAC cold side pipe, look for cracks/damage.
Also check VGT wire harness and plug for damage.
Check exhaust up-pipe and y-pipe flex joints for cracks.
Check for codes.
These are the easiest to check before running a OBDII diagnostic.

SO this morning I checked all the CAC boots and lines. all are attached and have no cracks. Checked the MAP sensor, it is still hooked up and clean. also checked baro pressure which was at 13.9psi and MAP pressure was at 13psi. the wire harness at the VGT was connected and clean with no damage

I took all the CAC lines and boots off and found a quarter inch tear on the bottom side connecting to the turbo under the clamp. I assume that this tear releases enough air for it to not build boost? any idea how much ford charges to replace all 4? or should i just go after market? riffraff diesel has a nice kit for $125, anyone used them?

How did you measure all if those temp and psi readings? I know it is with a guage, but is it a dedicated guage or did you take individual readings? I don't think I am asking the right way...do you have a computer hooked to your truck where you can get all of this data?

After that, you have the more expensive snap-on, IDS, ect,ect.
