Intermittent Turbo Spool-Ups
Hi, I have an '05 F250 6.0L diesel and have recently noticed that the turbo intermittently spools up despite the fact that I floor it. I sometimes have to wait a long time for the turbo to spool-up, and when it does, it does not reach the usual 35PSI. Any ideas? I was thinking that it might be a clogged air filter, but I only have 4500 miles on it. Thanks in advance for your help!

Still trying to replicate the intermittent spool-up... can't after I changed the air filter. Oh well, I'll continue test driving.

Yeah, I had to problem. It got worse over time. I thought it was the vgt solenoid but when I took it in they replaced the whole Turbo and vgt stuff all at once. I still think it was the vgt solenoid but oh well.
Mine got to where it would not spool up until the rpm's reached about 2300.

i have the same problem now with my truck. there are times where my turbo wont spool up at all 3rd through over drive. its bleeds boost pressure off real slow. the only mod that is done to the truck is a 4" downpipe and 5" exhaust which i think im going to change to 4".

Oh BTW, mine started to do it again this past weekend while pulling my stock trailer. Back to the 2100-2200 RPM before I get any boost which is a real PIA when towing over 10,000 pounds down the interstate.

Hi purplewg,
I forgot to ask.... was it a cold day when your spool-up issues occurred? It was a cold day for me. Not only that, but, I was mainly going uphill for about 10 miles. As I mentioned in an earlier post, I was towing my quad which only weighs about 400 lbs.
Also, did you replace your air-filter? I wonder if our porblems are due to intermittent cloggs in our air filters.

Well... the air filter didn't do the trick. It still has intermittent spool-up problems. I'm going to take it in now. I kinda didn't want to do that since it means getting my firmware reflashed. I heard too many horror stories about the reflash taking away power, making it quieter, and screwing the fuel milage. Geees! I hate putting up with problems on new vehicles!
