That's right they don't, but we do

We're working on a version of the Speed Brake for the 6.4L trucks now. And it's very close to release. It's fully compatible with the six gun tuner or it can be used on it's own. It's function will be EXACTLY like the system we have out now for the Chevy. I'll post a write up on it here in a second
