I have a 2011 2500hd. Its completely stock and I'm wanting to do some deletes and tuning. Iv talked to a local shop who has Cory Willis doing the tuning for EFI live. My question is what all do I need to delete and what are some safe tunes for a bone stock truck. I want to keep it safe on everything, it is my everyday driver. I drive mostly in town stop and go traffic. I'm thinking like 1. modified stock 2.towing 3.fuel milage. 4. & 5. Maybe some +HP but I'm not sure what is safe. Any help and advice would be greatly appreciated.
