Fuel filters clogging - change where you buy your fuel. Regen always on - could be a melted DPF pressure sensor. Seen a couple now.

Where are you located? -

Thanks to all for your help.

I ended up going with the Spartan Diesel Technologies custom programs for the DashDaq unit and the DPF Delete kit. This has worked out great. The DashDaq has much more flexibility than the Bully Dog. My truck never goes into re-gen mode now so my mileage has increased. I did the 75hp, 150hp and 210hp for the 3 tunes. I towed my 15,500lb 5th wheel throught the mountains of PA and over into Ohio using the 150 hp tune for the last week and got 11 MPG. I was getting about 8 MPG with the Bully Dog setup whith the stock DPF. My truck has a 411 rear end and iit never grabbed a gear when pulling the grades. I was getting upwards of 45psi Boost Pressure which was better than stock. I have a dully and if I dial in the 210 hp tune I can get a 2 gear burnout on dry pavement. Not to bad.

The extra power is there when you go with this system. I would highly recommend it.

The Bully Dog was a huge waste of money, a big disappointment and certainly not designed for vehicles with DPF setups. -

Tom, how much is that kit that you bought? Did you do anything else to achieve the 11mpg besides the kit?

Thanks!

45 psi is a LOT of boost.

Do you have a free flowing air filter and exhaust? If you don't have a free-er flowing air filter, the turbocharger will suffer harm making that much boost without allowing that much air in. -
