I'm new to the 6.4 and I'm looking to be doin the dpf delete. I found a live wire competition ts for a good price. Should I get that or should I find a 9625or or 3015r. I plan on getting custom tunes from idp, when I talked to idp they told me I needed the 9625 or 3015, offroad. I'd hate to spend money on something that won't work on my truck.
