Reduced Engine Power - Diesel Forum

TheDiesel · 08-22-2011, 01:57 PM

hey everyone i am new to the forum and also to diesel pickups. i have to say that i love my ford powerstroke. i bought a used f-350 with 80,000 miles. i bought the pickup because i have been pulling a lot of trailers with my construction business. i was pulling a bobcat and the message came up that i now have reduced engine power even though it didn't feel like i lost any power. i only get this message when i am pulling a trailer. i would appreciate any input that you have on this subject. thanks by the way my truck has the DPF removed and has a edge programmer in it.

Did you scan for codes? Also do you have the updated ford flash 11B23? Any high engine temps?

TheDiesel · 08-22-2011, 09:57 PM

no codes and no high engine temps

ok i lied there are three codes that showed up on my programmer they are P0234, P115A, and P1000. anyone know what these are

P1000 just means the OBD test was not completed..ignore that one
P0234 is a turbo overboost condition
P115A is reduced power because of low fuel level. It was trying to keep you from running dry which is a bad thing.

Probably the P115A might have been from a previous time?

ya it was from a different time. i just dont have any idea of why that message would show up. and like i said before it doesnt feel like the engine power is reduced. if i had to guess it would be that code that is the turbo overboost. do u think that i should tune my truck back to stock the next time i am pulling a trailer?

Yes, put it to stock. That overboost will throw it into a reduced power mode.

also how would i go about getting the new ford flash that you mentioned? and would the mini max be a better tune for me to use if i am going to be doing a lot of towing?

The ford flash was in the form of a letter that was sent to all of the owners. It is free. Stop by and see your service advisor with your vin. If you need it then it will show up.

Truck needs to be put to stock for this. I would advise leaving it in stock form for awhile after the flash so you can see if there are any issues.

As far as what tune to use for towing..I prefer in stock power as I tow pretty heavy.
