2008 F-250 No Turbo Boost
Okay, my 2008 F-250 with 46K had a plugged DPF and went to "Drive to Clean Exhaust Filter" and I drove it about 50 miles without clearing the warning. Instead, the warning changed to Reduced Engine Power. Now I have no turbo boost as the peg stays on zero. Anybody had this problem before?

Your truck should be under the 5-year, 100K engine warranty. I'd strongly suggest taking it to the dealer for them to figure out.
Could be a lot of things...bad turbo, engine damage, high pressure fuel problem, etc.

No Turbos...

I made it to the dealer and left it there last Thursday and it's still there. The first thing they told me was the diagnostics said the DPF was clogged. Then they called back and said it wasn't but they needed my stock TAILPIPE. I dropped it off Saturday morning and have heard nothing since!

Correction to my thread where is said "Okay, I get a reading of zero for the bp on the truck with the engine at a very rough idle" the bp was not for back pressure, I meant Barometric pressure. Thus, my reply should have been:
"Okay, I get a reading of zero for the barometric pressure on the truck with the engine at a very rough idle. Is the BARO sensor the MAP sensor(my quick reference code book show a slash between like the two sensors are the same sensor)? Bad MAP sensor? If it is could somebody please tell me where the sensor is located?

Lots of misinformation here...
His exhaust filter isn't plugged, something is wrong with his truck.
I saw the "drive to clean exhaust filter" message several times on my '08, all of them under 15,000 miles on the odometer. This means that the truck need to be driven to complete it's regeneration cycle, NOT that the DPF needs cleaning.
If the DPF were plugged he wouldn't notice any erratic idle. It's like an air filter, if clogged you will notice decreased performance during high RPM/high power situations, but idle will not be affected for a LONG time. He would have noticed driveability problems long before he noticed an erratic idle.
My guess is that there was a problem with one of the exhaust backpressure sensors which caused a long, 50-minute regen cycle. Something probably let go, after sustained 1,100°F EGTs caused by the regen cycle.
The DPF isn't clogged, the truck is broken.

For whatever reason the info I read is not in the 2008 owners manual, however if you look at the 2010 owners manual, 2nd edition it states
DRIVE TO CLEAN EXHAUST FILTER (Diesel engine only) —
Displayed when the Diesel Particulate Filter (DPF) is full of particles
(exhaust soot) and the vehicle is not being operated in a manner to
allow normal cleaning. This message will stay on until the exhaust filter
cleaning has begun, at which time the CLEANING EXHAUST FILTER
message will be displayed. It is recommended the vehicle operator drive
the vehicle above 30 mph (48 km/h) until the CLEANING EXHAUST
FILTER message turns off. This message is NORMAL. Refer to your
Power Stroke 6.0 and 6.4 Liter Direct Injection Turbo Diesel Owner’s
Guide Supplement for more information.
Note: If this message is ignored, your vehicle will continue to fill the
Diesel Particulate Filter (DPF) with particles (exhaust soot). If cleaning
is not permitted, the (wrench light wouldn't copy over) light will illuminate and engine power may be
limited. If the vehicle is still not operated in a manner to allow cleaning,
the service engine soon light will illuminate and engine power will
be further limited. Dealer service will then be required to restore your
vehicle to full-power operation.
