I have a local guy that wanted to do a DPF delete, he bought a pipe (not sure which brand but it does have all of the bungs for the sensors).

So I used my HPtuners to tune out the codes and set the DPF to disable and 0.

He did not want me to tune the motor and fuel because he uses a Diablo trinity and likes to be able to change the settings while towing.

So I took his stock tune and did the changes, then he used his trinity and loaded my tune as his stock then loaded his trinity in.

I noticed that the trinity kept the codes disabled so his lights wont come on. but changes the DPF back to enabled and 1.

I am thinking that his truck is going into regen mode and causing his poor mileage.

I am trying to convince him to just stick with the tune I put in, but he won't.

Anybody else run into a similar problem?

I checked HP Tuners acronym list to find out what DPF means, but even they didn't list it.

Oh yeah probably should say that it is a 2008 GMC 2500HD 6.6L LMM Diesel

I think this needs to be asked on a diesel forum, I had no clue on the acronym either. I don't think there are many diesels guys here. JMO

Can you read the tune the trinity puts in ?
If so, why not just read that one and then delete the DPF in it and flash it.

Because the diablo takes the base tune to modify. I dealt withthis on an edge with just a cts monitor on an lmm. Changed it to no and 0 and it worked fine. If he wanted to ditch the diablo he'd be better off.

Yeah the guy doesnt want to get rid of the Diablo so I guess that it is on him instead of me. O well
