Mini Maxx/Regen/EGR valves

[Wtrski413]

So I installed my new Mini Maxx last week. I live in CA so the DPF and EGR stay on (random checkpoints). The Mini Maxx is great but I still have not Regen with the DPF on tuning. Any thought's? I used to Regen every 500mi or so and now I have traveled over 700mi. Also with the mini maxx, does it cycle the EGR on startup? I emailed the H&S tech but haven't heard back from them.

The EGR will operate as normal with DPF present tuning. I drove for a week with DPF present tuning while I waited for the delivery of my exhaust. Didn't see much benefit out of it and it regenerated more often. Are you sure you didn't just miss a regen in there? Sorry about the state of residence...!

do yourself and your truck a HUGE favor and buy another DPF and hollow it out

Yeah, if you want to know the details of that, I recommend shooting a PM to antonm, he did that to his...

I've done it. works great. don't hollow the cat and the truck will still smell like it "should" and you won't get the insane turbo sound. run it on a mild tune and turn the smoke down as much as possible and ENJOY

No way... the smoke is great for tailgaters...

Thanks Ruffstuff for he reply. Thought I read somewhere that the EGR cycled on dpf present tune but I wanted to make sure. As far as a hollow DPF, how much does that cost?

Here is the info from the H&S website:

"When running DPF PRESENT tuning, it is required that all sensors located in the exhaust system stay in place and plugged in, otherwise you may experience a Check Engine Light (CEL) and even a loss of power (limp mode).

When running DPF REMOVED tuning, it is recommended that all sensors located in the factory exhaust system be unplugged from the electrical harnesses. These sensors can also be removed completely with the factory exhaust if desired. On the 6.4L Powerstroke, there are usually 2 EGT Sensors and 1 Pressure Sensor.
Note: The vehicle will not run with sensors removed unless DPF REMOVED tuning is installed.

When running H&S DPF REMOVED tuning, it is not required to unplug or block-off the EGR system on your 6.4L Powerstroke to disable it. The EGR system is already disabled in the tuning and will not function under any conditions. If desired, the entire EGR system can be unplugged, blocked-off, or completely removed when running H&S DPF REMOVED tuning."

Yeah I read that too. Thank you. But do you know if it only cycles at start up/idle? I was told that is the only time it cycles and at normal operating temps it's off with DPF present tuning.

I sure don't.
