Guys,
I'm new to the forum and need a little help. I recently added a Bully Dog Triple Dog GT to my 2011 Duramax. Since adding it I am experencing way more regenerations than I was getting stock. Before the tuner I was about 1 regen per tank. Now I am experiencing a regen about every 100-125 miles (about 4-5 times per tank). I am not running the truck hard, just normal driving. What would be causing this? Anyone else having this problem with this set up? Is this going to damage the truck over time? I have contacted Bully Dog but can't seem to get any real answers. Any help would be greatly appreciated. Thanks.

I had the bullydog tuner for a few months until H&S released their tunner. I experienced the same thing, had about 3 or 4 regens per tank. The more city and driving I did and the more i abused the truck the more it went into regen. From what I have learned this is normal. The tune is essentally burning more fuel for more power which makes more soot that the DPF Filer needs to clean, therefore more regens. The only way to get around this is call H&S and remove the DPF. You will be :)

How do you know your truck is going into REGEN?

the easiest way is the elevated idle 640 rpm up to 800 rpm during regen. If you are able to read egt you will see them up about 200.

4-5 regens at every 100-125 miles means you are getting 400+ miles per tank of fuel?

Yes. 36 gallon tank. I'm getting 530+ miles per tank right now. I do like the power gain. Just not to impressed with the constant regeneration cycles. I just hope it doesn't have any long term effects on the truck. The way i'm thinking about it is like this: At 100,000 miles with the tuner, the truck will have regenerated as many times as it would at 400,0000 miles without the tuner (before I was regenerating 1 time per tank on average)
. I just wish Bully Dog would have disclosed this information before I spent $700.

Ouch, 4-5 regens per tank. I hate having the regen just once per tank.

Wheres BullydogJason at? Maybe he could help out with answers.

Only truck ive had experience with is a stock 2011 with the GT, it does a regen about 1 per tank on the performance tune, that is with majority of highway driving, maybe 75/25

do you have the 1128 software?

You probalby be happy going with the h&s to or just see if you can ge ride of your constant regen with the bully dog

my seem to regen all the time and i dont have a tunner I HATE THIS REGEN CRAP 100K MI ITS COMMING OFF.

I am assuming that all the extra regens is because the truck is in the highest power setting? If its in the lowest one, I assume the regens will be alot less frequent. I am wanting to buy one but if its gona regen every 100-125 miles.. No thanks!

The more city and driving I did and the more i abused the truck the more it went into regen. From what I have learned this is normal. The tune is essentally burning more fuel for more power which makes more soot that the DPF Filer needs to clean, therefore more regens. The only way to get around this is call H&S and remove the DPF.

This is exactly whats happening. You up the power, it creates more exhaust and soot which then clogs up the dpf faster. its the price you gotta pay if you want to keep the DPF and have a tuner on your truck.
