Check engine light with H&S

[sledfreak]

My check engine light won't go away no matter how many times you clear it or how many drive cycles like 6 in 200 miles and pulls no codes but as soon as you put it to stock the light goes off.Have downloaded full sd card and it changed nothing the light stays on any thoughts?

What version of tuning are you on?

And I am guessing DPF Present?

We had a couple of trucks getting codes on DPF Present. The latest update addressed a few of them, but let us know if you are still getting them on the latest software.

If you have a Mini Maxx:

Mini Maxx Update Log 6.4L Powerstroke - H&S Performance

Black Maxx:

Black Maxx Update Log 6.4L Powerstroke - H&S Performance

Sledfreak,

I hate to bother you, but i have a few quick questions about your H&S with DPF tune. I am seriously thinking about buying and Mini Maxx, but i have to leave my DPF on. Did you see any increase or decrease in MPG? Also, how often do you regen?

Thanks!

Turbo kid,i've had mine on for a couple of weeks with the dpf present,regens have become more frequent therefore milage has suffered,i would not recommend it if your going to leave the dpf on.True milage gains are going to come with it off,i had a trans issue that was under warranty,that had to be fixxed and was working 12's, so i had no time to take it off yet, but will soon.
