No, you can have the deletes done with the 30hp tune. If you need to do emissions, I would do one of two things. Leave the equipment in place, or pull it off and then put it back on when you do emissions and just flash back to stock until you have done the testing. This is 'easier' for the DEF than the EGR, MHO.Assuming 30+ for emissions and 60+ is for deletions?
I don't have emissions testing here, so I am not worried about that. I'll pull off the DEF system and keep it in the garage just in case.
Next phase is the EGR delete with the Banks intake.
