DPF DELETE KIT??? - Diesel Forum

atx512 · 01-17-2012, 11:21 PM

has anyone done the dpf delete kit on this truck? im thinking that im going to do it by the end of summer

Jayybird · 02-14-2013, 02:21 PM

Where o where can i find the instructions on how to do this?!?!?!?!?!

I want to have a clue as to what i am doing before diving into this. What do you do with the sensors? probes? Getting the actual DPF out of there looks simple as it just bolts in bolts out. But the electronic mess going to it is my concern...dont want a mystery check engine light to come on and have to put all that mess back together and bring to dealer and be like...."uhhhh i dont know what ahh happen"...

THanks any info or tips or write up would be mostly appreciated.

As far as I know unless you have a tuner before they changed them. The new ones only have tunes for trucks with all that intact. IV been looking to and this is what iv foun .

its pretty straight forward, you are removing an existing pipe and replacing it. Remove the sensors, unbolt it. reverse to install. A DPF Delete pipe will have the spots you need to screw the sensors back in.

So the sensors reconnect to the delete pipe???? I have been told the following,

1) disconnect sensors from dpf and tie wrap back
2) only disconnect the sensors at the other end, not to disconnect from the dpf
3) what was said above...

I just got an older HS that does dpf off tuning

Delete pipe on its way

Some say disconnect EGR, others say no, a few say block it...

I am gonna dive into this. Sure hope I don't have a cluster F

All you need to do is unplug the sensors from the DPF, remove DPF, intall delete pipe, tune truck. We put electrical tape over the connectors on the truck so they don't corrode. Had no problems on re-install when I sold the truck.

I think your install will be pretty easy, just hopefully nothing happens to the truck once it's done. Deleted 6.7's are notorious for puking turbos.

Thanks for the input!! Puking turbos...excess heat due to a heavy foot I suppose? Y'all recomend a pyro?

I've been following all of the DPF delete posts as I will probably do this before my summer trip. However, I don't want to destroy anything. So, what is a 'puking turbo' and what exactly causes it?

fulltimer50 · 03-10-2013, 12:30 PM

Generally when a turbo fails the turbo shaft oil seal fails and "pukes" oil into the exhaust pipe. If not caused by running the engine without oil pressure (ie starting with an empty oil filter) the failure is usually caused by over pressure, over reving, or over heating the turbo.
A tuned engine removes the safegaurds to prevent this from happening.

Thanks Fulltimer. I definitely don't have a heavy foot, always wait a about 15 seconds after turning on the key to start, and am overcautious about approaching 1250 on the Pyro. Where does the over pressure come from?

Nickelplated5s · 03-11-2013, 09:52 AM

More pressure = more air = more power. Old systems had a pop off valve that determined max pressure. You've got a variable vane turbo, it can be commanded to produce more pressure rather than change the pop off valve. Go read the other thread too.

Thanks, Nickle; but you lost me.

I did mine when it had 10 miles on It I now have 21000. No problems the only failure has been the radiator LEAKING.

Part of the way they make more HP with a tuned engine is to produce higher pressure with the turbo. If you watch your turbo gauge you almost never exceed 20 psi of pressure. A tuned engine will push that pressure higher. I don't have a tuned truck, so I can't say how high the tunes push it, But for this discussion, Lets say they go as high as 30 psi. Back in the old days, You had a wastegate that opened when you developed too much pressure. With the new variable vane turbos, the pressure is controlled more with the vanes instead of the wastegate. The tuners have the ability to program the vanes to hold pressure higher.

Hence the risk of a puking turbo.
