not sure if anyone saw the other post. i pulled the trigger and bought a stillen last month, and i did not notice where it said it would not work with the active areo shutters. i got mine on july 5 2020 and put it on the truck. after instillation i noticed that the areo shutters was very close to the mouth of the scoop, the didnt touch but was very close and looked like it would restrict airflow when they shut. but i didnt have time as i had to make a 560 mile drive back to Michigan for work. made the drive just fine got close to 20mpg on the drive (not bad for a 6.2L 4wd cruise set to 80). got back to the motel and started looking into the areo shutters, a and from what i could find they close at like 50mph to help with aerodynamics. i then started searching the web to see if anyone had modified the shutters, but looks like no one had done much with them. so i was like heck i'll be the first. went out and removed the top left and top right shutter. ( would have been much easier had i removed the scoop, but i didnt have any tools with me to remove it) i just carefully bowed them and popped each one out. the shutters still function as normal except if crams air down its throat, and picks up a bit faster on interstate. i have not been back home to see how it does on a long haul since removing the top shutters.
