03 Problem, couldnt pull a 3k lb boat

[cryptnosis]

Vehicle: 2003 F-350 King Ranch Crew Cab 6.0L

I have in the past pulled a 2005 Infiniti FX35 with no problems at all, my friend asked for help pulling his boat (3000lb with trailer). Should of been a cake walk.

As soon as we pulled out of the parking lot with the trailer attached we noticed it seemed not to have any power at all. Then when we went up the first hill with the pedal to the floor, we were barely able to maintain speed and we heard a TON of air under the hood. and everytime we tried to accelerate we would hear a TON of air under the hood.

we finally made it to the destination, and after we disconnected it seem to run fine (without the noise).... i have 2 codes thrown ... p401 and p132 ... I am trying to figure out if this would be associated with the EGR or turbo. Any ideas?

Just wanna say f it and buy an egr delete kit with a sct programmer.

Did you blow any smoke while not having the power?

[cryptnosis]

no ... no smoke

small tear in a boot, etc? not allowing max boost but under normal driving 5-8psi you may not notice it... I have heard to get a mirror and check the underside of the boots, thats where the majority of most tears occur. I would think that would toss black smoke but maybe just enough boost to not notice.

you have a lack of power and an EGR code (401 , not sure about 132)

I would suspect a stuck open EGR valve.

The noise under the hood makes me think blown boot or leaky exhaust connection (most likely blown boot)

I am going to get an egr delete kits this weekend. Going to switch my o2 sensors to see if it transfers codes. will keep up to date

[PSDMikeB]

hmmmmm O2 sensors? I have had mine torn down pretty far and don't recall an O2 sensor????

Do you mean IAT? Not sure if they are interchangeable. Mine has a combo IAT/MAF for the IAT2.

No such thing as o2 sensor on a 6.0......

<<<< noob at diesels... P132 said it was a high voltage o2 sensor. I assumed that right after the headers was where the o2's would be... I take it that diesels dont need o2s to measure how much fuel is burnt?

what kind of code reader are you using? Some do not read the power strokes very well since the "heavy" trucks did not need to comply with the OBD-II standard.
