I for the time being have the crap TB in question. The only reason I went with it was all the local dealers did not have any other 75mm in stock. I was tinkering with it while we were picking up some other parts, and sure enough the plate stuck wide open when I maxed it out. We switched it for another, but imagine if it was on the car. It's on my first to change-out list when I get to it. So far though no problems with this one.
