I'm new to all of this. I'm wondering what would be the best tuner to put on my 08 6.4 that will delete*egr*and dpf/cat and also not throw any codes or have the check engine light on. I'm only wanting to delete the dpf/cat,*egr and make the exhaust loud and throaty . I don't want a big tune or anything. Just wanting to do what I stated above. I cant stand how the truck sounds stock. Would like to have tunes on programmer so i wont have to spend alot on custom tunes. I dont want to spend 1500-2000 on a spartan because i wouldnt use its full potential. What's my best option?
