Recently my 2007 has become my DD. So after 9 yrs I've purchased a
DPF delete EGR delete with a H an S mini maxx. I will being doing the work myself. The question I have is there a stopping point between any of the work. Like can I do the EGR one weekend an do the DPF the next with the tuner install the following weekend.

I know one (or more) of the H&S tuner models will allow individual deletes/disables but I don't know if the MM does it. You can plug it in and see if you have individual options for the egr and dpf. If so you can load the tune with only the egr delete running and do that one weekend and then reload the tune next weekend with both egr and dpf selected for delete.

Or you can just unplug and remove the egr system for a week until you load the tune and delete the exhaust. You'll get a P0405 code until the tuner is loaded but its no big deal.

Any way you look at it you'll need to load the delete tune the same time as you delete the exhaust.
