no Boost indication, too cold for my baby??

[sotarcat126]

05 F250 SD crew 6.0L Spent the Holidays in eastern Montana, very cold -10 at night on the way home got the engine service light and checked the manual and all I got was an emissions issue/bad fuel, I am all for the bad fuel as it happened shortly after fueling. A short time later I notice that my turbo boost gage was showing minimal boost, at full throttle climbing a pass I could barely keep it at 50 mph and maybe 3 lbs of boost (I could hear the turbo spool up tho) . Now I am home (western Wa) and its the next day, lights still on but I now have my boost indication back?????????

Are you running any centane boost in the fuel to keep the turbo and EGR valve clean. You could still be having turbo problems some of the veins could be frozen or a bad unison ring about once a week after you warm it up you need to drive it like you stole it to keep these parts clean and if it sets to long the turbo will rust.
