I ended up pulling the trigger on the used Kong 112mm throttle body. The poster said he was selling it because it "is known to not handle high levels of boost and can go into limp mode." He also said the Greg didn't have a boost number but it should be fine under 800 hp. I was just curious if anyone had heard this before. The only reference I could find of one going into limp mode was on a hellcat but I found other posts of smaller throttle bodies causing the car to go into limp mode.
