Black Maxx and DPF

i installed a black maxx and s&b intake on my truck, and have just been running the mild setting as i havent had any desire to do anything with the exhaust. ive noticed over the past few days, egt's were getting higher and higher, boost lower and lower. i havent gotten any codes or engine lights, but it has pretty much completely quit boosting and runs 1000 degrees at 40mph. im guessing the DPF is clogged? i havent noticed a regen in a while. theres 100k on the truck. what do i do to fix it? if i program back to stock, will it go into regen and clear it up? or is the DPF toast at this point?

thanks,
mike

I think you may have nailed the issue. You invested most the cost of a dpf delete, so why not put another 200.00 for a pipe and get rid of the dpf?

I think you should try to put it back to stock to burn the DPF out and then buy yourself a delete pipe.

Sounds like your DPF is pretty clogged. I hope its not too late.

Like the guys above say, it may be time for a delete pipe. With 100K on the clock, the DPF likely was not in the best shape. The added fuel from tuning may have pushed you over that fine line that leads to a plugged DPF.

Or you can try to do a nice hard run on the freeway and build up some real heat to burn out the DPF. Put the Black Maxx back to "no power" and hit the road for 20-30 miles.

Also think about all the additional fuel going into the pan.

agreed with all posts above, invest in a DPF delete pipe...shouldn't be too expensive. Call Rudys or there are other vendors on here with great cred that will give you a great price. That should solve your problems.
