I heard that about the encryption but it’s been cracked by Livernoise and I think 5 Star for sure. I found a post/site for some tuning via ecm flash by a fella up here in the Great White North, I contacted them and I am just waiting to hear back. It’s not ideal to pull the ECM but he’s close enough that maybe a guy can just drop the truck off.I just got my 2021 truck back from aFe, they test fitted their air intake system, intercooler & tubes, exhaust, scrocher Pro & Blue (tuners).
Only items that worked are the air intake and exhaust. They had to create a wiring harness extension for the MAF sensor though.
They said Ford in 2021 put in new encryption in their computers making it even harder to tune, just have to wait till someone can unlock it.
