Can I ask who you went with for the unlock and which tune?
I had a 2018 6.2 and had custom tunes done by a guy on the forums called “diablew”. He really woke that truck up.
Now I see that I can finally have my 21 TB 6.2 tuned and I think you are the first on here to mention you’ve done it. Please share who you went with and how much of difference have you noticed.
