Ox50

I have closed the egr valve using premium tech tool while it’s running seems to me like when I do it runs like crap so I was thinking it was good to go I went out this morning and see antifreeze laying under the truck coming from the exhaust system 

Yeah it’s a coal hauler in southwest Va 65 bogie 12.00x24 tires triple framed 

Thanks I’ll take it off give it a shot 

Yeah I kind of been hard to maintain air psi on the secondary side no power steering issues and I will try the clear hose do you happen to know what size hose I’ll need off the top of your head 

It has gotten worse overtime seems like when you first pull out in the truck it will run good then it just stumbles won’t build rpms or boost kinda like it’s not getting fuel just not having the hard starts like every one says they have when it’s the cups I’m just trying to get more info before I spend the money on it 

Eaton fuller 18spd 

Honestly idk the I just bought the tube had it installed it done great for awhile really not thinking it’s a tune issue there’s something else going on I just haven’t found it I’m leaning towards injectors and cups 

Not much of a difference in sound when the truck runs right my isx can’t hold a light to it we haul big weights in steep terrain the Jake brake is unbelievable on this thing 

Yeah I had the delete done when I first got it it just currently went to crap but yeah there is a delete file flashed to the ecm 

Yes this truck was equipped with def but that had been deleted 

Vgt turbo actuator is good according to the test I done on premium tech tool auctually took it and recalibrated just to give it a shot 

I wouldn’t consider it hard starts just no power I uploaded some pics of the injector rates from earlier today the truck is deleted when I first bought it it ran great the first few days auctually a little better then my isx 565 but shortly after it started running really sluggish in the mornings after a couple loads it would start to run better through out the day but still not what it should have been I know I’m not getting straight to the point just trying to give more details what I have been going through since I have owned it sometimes the trucks runs good builds boost through a few gears then it just falls on its face 

I’m having issues with my 2010 gu713 I’m thinking it’s injectors and cups but not completely sure just trying to get some insight 

Any update I have a similar problem at times my truck will run at 65% others it’s just dead in the water not building boost 

Did you figure the issue out?
