So I’ve had my AT4 for a couple of months now coming from a tuned and deleted LML Duramax.  I’m missing the power, has anyone supercharged their 2020 6.2 yet?   I’ve done a little research and realize that the pro hanger kit has been released but haven’t read any reviews of any installs.

The tune is what will get you.  HP Tuners is the only one available and as I understand it, is north of $3,000.  You still can't tune the TCM.

Right, that is really what is holding me off right now.  Seems silly a 1/3 of the cost is the tune.  Hopefully someone can come out with some better options.
