yeah its totally okay! its custom tuning for the duramac and cummins engines, you can basically do whatever you want as far tuning goes and it is amazing. i highly recommend talking and getting your stuff from Idaho Rob at ATPtrucks.comWhat is EFI live? Sorry but I'm totally new to the duramaxx and to diesels.
Exactly what you should do. The 2010's get worse mileage STOCK, but you can do things to them to get better mileage than the 2011's. The urea is for the exhaust, yes, now there is really such a thing as exhaust fluid. It is for the particulate filter so it doesn't use your extra fuel like the 2010'sI'd simply out it this way... if you want to mod the truck and make a lot of power, buy a 2010. If you plan to just leave it stock as the day you get it, the 2011s are pretty awesome trucks.
The emissions stuff wouldn't be a deal breaker for me, as the 2011s get awesome mileage stock. And either trucks emissions equipment will work as designed without problems.
