Patience is running thin!

With this truck.......... Winter hit hard and fast mid october and hasnt let up. 170+ cm of snow (records for here) in last six weeks and its been no warmer than -20 either

First I got the transmission issue....had to change out temp sensor. Drop pan, new filter, new sensor and 10 litres of mercon. Done in driveway, -22c. Done.

Following week (last week) get another CEL.....P2263/P2563. Ok. Clear codes, come back couple day(s) later. Do some research, remove EBP sensor and clean thoroughly. So far so good.

Today I drive to and from work, everything normal. 2 hrs later I go to hockey and I can feel the truck is acting strange. Turn music off, check over dashdaq/listen to the ol girl and realize im hitting low/mid 20's psi at like 1/4 throttle doing 40/50 km/h!!! Wtf?!?
I give er a little more sauce and hit 30 no prob. Driving around town I veryyyy rarely ever hit high 20's let alone 30's unless Im getting frisky on er or hitting some hills and hit it good.


Im running spartan 300 (re-flashed when had trans issues). 4x4hi engaged almost always.

Rant over. I suppose Ill try a re-flash again, maybe go to a lower tune for the winter as well.
I still love my ford (for now )

i'm glad someone is using the truck for what it's made for! haha

I can only imagine how tough our trucks are to be able to handle temperatures and conditions like you live in. I live in SC. It barely gets below freezing down here during the coldest parts of the winter.

Sorry to hear your issues, but keep in mind your issues could be a whooooole lot worse! Good luck bud.

Are you throwing an overboost code?

[Clayton1985]

Thanks Wilson.
No codes. If there was I could get code and go from there but nothing. Its running id guess about 2x whats been the normal!

[6.0f250firstcar]

So the trucks running fine but the boost is high?

[Clayton1985]

Correct. .

Well is it possible your turbo veins have always stuck and just opened up? Sorry I'm not as good with turbo problems lol.

No worries man! No, truck has always ran great/normal turbo wise then out of the blue it acts up. I believe it to be tune and/or weather related. I havent had truck out today so no new info, im going to re-flash tune though.

[Clayton1985]

Was still doing it this morning. Left truck in shop while I was on job. Drove normal on way home from work......Must be the weather I guess

(warmed up a bit today, only -10ish now)

Air is much more dense at colder temps, that may be why you are seeing higher boost pressures?

-22c isn't too bad, it's been about that and a little colder here the last few weeks (finally warmed up and we got a little bit of snow). It seems like it's hard to get her to stay below 10psi on cold days, also FYI the tranny actually has 2 4th gears, it uses a slightly lower 4th gear in cold temps, so that also might be what you are seeing.
