I've never run one, but I'm convinced that the Red Brick needs one. I had it out on Skyline Blvd one day a couple of years ago, which is very twisty. There was a distinct lag as you turn the wheel back and forth. It has a Stage 3 FF box in it, so I doubt it is the Mopar on-center dead spot. I think the box was flexing on the K member, but I have no proof, just a hunch based on the fact that everything else had been thoroughly dialed in on that car. It was on my list of things to do if I had kept it.
