"The" DPF removal write-up

[Dragbear]

Hi everybody
I just got my v2 today and tried to remove the DPF using some of the post about doing it.
It started up ok with no dtcs so I took it for a ride. First 3 miles were ok then it started surging and putting out a lot of black smoke. It felt like it was going to quit so I got it back home and put the H&S back on it. It runs great with the H&S mini max. Any Ideas???

I have the H&S sold but I have to get the truck to run with the EFI first.

Remove the H&S, go to the dealer and have the ecm flashed with a clean OS. Read the clean OS and tune from there. The H&S has the OS segments all messed up. I have a customer running with DPF, he flashed with H&S and had the tuning all messed up, then he brought it here and after fooling around for a day I took it to the dealer and got a reflash, problems all vanished.

Please leave us know how it works after a reflash.

As Lee said, I have also seen this with Diablosport.

Post up your stock tune that you have, and I'll see if I can correect it for you. There are ways of fixing the segments in many cases, but it isn't always easy.

I am very new to forums and I'm not familiar with EFI Live other than everyone says it is the best available. Anyway I have a Chevy Express with the LMM and have installed the 3" downpipe and a Magnaflow 5" filter back kit and just drove it and the clean exh filter light appeared. I want to eliminate the DPF system for the benefits anyway and need direction in the sense of a written tune to allow this. Not looking for anything extreme just mild but no DPF. Any help is much appreciated. Thanks

e-mail me your tune to tune@torquesouth.com and I will have a look

Also, do not be so direct with describing those kind of things here. It is frowned upon as it can be misinterpreted by some to suggest that you would be looking to do something that breaks emissions regulations. Clearly this is an off road use vehicle.

Any luck figuring out the, p0546. Got one throwing this code, but haven't gotten a chance to diagnose the problem. Will be looking at it on wed. And a specific area would speed up the process. Thanks

I just did another DPF delete and there are a couple codes that will not go away..... I have never ran into this. Codes are p2033 for the EGT sensor 2 high voltage and then p0546 for EGT sensor 1 high voltage and then p2455 for DPF Pressure sensor circuit high voltage. I have never had these problems before so if someone that has and would like to pitch in and help me resolve this it would be great

Any luck figuring out your codes? I have the 0546 and a specific area would be great

Never mind. I missed that DTC when I was setting to not report
