Shiner, are you deleted and if so how do you handle the emission testing? I've been toying with the idea of deleting for years but more so now that I'm out of warranty. Only problem is I have to get tested every other year now in my county. I'm not sure I would flag or not since the tuner should quash any emission related flags, but I really don't want to deal with putting everything back on every other year.
Yes, and there are no emissions testing for diesels where I live in Texas. My cousin, who is also deleted, lives near Travis county so he has to get an OBD emissions check that makes sure there are no codes. None ever show up because the tuner turns them off. Keep in mind that we don't roll coal and get ourselves noticed.
Another option is to do an emissions intact tuning which basically turns off the EGR and uses the SCR more so all of the emissions are taken care of after then engine so it can run more efficiently. Power wise this is just a little less than a full delete of the DPF/SCRm but you still have to worry about emissions system failures.
Keep in mind that if you do a lot of city driving, you will likely not see much of an improvement in mileage with a delete or emissions intact tune. The more highway or steady state driving you do the more gains you will see in regards to mpg.
