Mine arrives today. You can use the coupon "Save" and it saves like 5 bucks. Make sure you select the ZL1 option. I too wanted to have control of how and when the valves closed without pulling the fuse. I installed a Corsa NPP and when the valves close on it, its like hitting the mute button. Very very obvious that they closed. Its a shame there isn't a way to adjust the valves in HPTuners.

it stops at model year 2019, I was asking if anyone here had any knowledge of it still working with model year 2020
