Yeah i dont usually pick on someone's opinion but i just dont really understand the thought process. It will cost you time (break downs, headaches, dealing with service techs, getting loaner cars, going back and forth to the dealer) and aggravation now AND then time and money later. Or your can just you can just solve it all with the same amount of money now and be done with it. Both people who posted are having issues with the emissions, it has nothing to do with deleting being a "preventative measure." The entire thread is about them and their cars... not your car.
-Yes deleting is just the easy way out.. but it is not more costly if you plan on keeping the car for a long time, because you wont be paying to keep the emissions in place after the warranty is gone (if you've seen what the prices are for any emissions fix you WILL delete when the warranty is gone, its cheaper to delete and tune).
In addition you will be saving fuel money... for me that equals about 125 gal (getting 4 mpg higher based on fuelly data) per year.
-The amount of regens and length of regens was much worse after the fix.... i was driving 200-300 miles a few different times per week pre-delete and i was astounded how often i finished a long trip with a regen going, that never happened pre-fix
