it's really a small amount of money when compared to the price of the truck. take $1500-$2000 (less if you like) of the HUGE savings you can get on a new truck right now. do the deletes, and you'll be good. even with the money you've saved on your purchase, that will go a long way to fix any problems that might arise. who have you read about having troubles with the emissions deletes?? that is what fixes the problems these trucks have.
