torqx screw driver
flat head screw driver
first off, take the two torqx screws out and slide the TB blade out, then with the flat head screw driver take and pry the restrictor plate off, i sealed the two holes back with steel rivets but epoxy or silicone will work as well. NOTE IF THE 2 HOLES ARNT SEALED CORRECTLY IT WILL RESULT IN HIGH IDDLEING ISSUES!!
RESULTS 25% more air flow

that't the first thing I did on both of my OBS trucks when I got them. I like the better response, and I'm sure it helps some, even if not a lot, at WOT. Good mod and free for me!
