First off i would like to start off with an apology if I posted this in the wrong area, I am new to posting, but have been doing months of extensive reading through this forum and must say thanks for all the help in which it has provided me.
That out of the way, I've searched high and low through the site and have not been able to find any posts related to my issue, hence my reason for posting.
My problem is; a few months back i purchased a Gearboxz DPF-r 3.0 module, and delete pipe for my 08 mega. Everything has been working fine thus far, except whenever I wait the specified 15 seconds to clear my DTC's and reset my counter, the truck produces white smoke at idle. This happens with and without the exhaust brake on, but worse with it on. It also does it whether the engine temp. is hot or cold, and boy it reeks like diesel. I read that the ex-brake can push the egr open and cause this. so I deleted the egr, and the problem persists. Initial thought is regen, but not 100% as it does not do this if I start the truck up right away and not wait the 15 seconds.
All i have done to the truck is DPF, muffler, and EGR deletes with the DPF-r module, and removed the throttle valve gear.
PLease help, I'm really looking for an explanation as to why this is happening, and what exactly is taking place. Also suggested remedies are much appreciated.
This is my first diesel, and trying to learn as much as possible, I understand they can take alot, but the horror stories of these new 6.7s have me really shook. Just want to make sure anything and everything i do to the truck will be beneficial to both the longevity and operation of the truck.
Thanks alot in advance. JB
