I used one in a 8.25 for a while, and it locked like a spool when it was locked. It would ratchet OK around tight corners like stop signs, but it needed a little bit of gas to ratchet around longer corners, like at larger intersections. If you just coasted through those trailing throttle, it would pop really loudly as it was forced to ratchet. Just a little gas would cure that, but you have to be conscious of that fact when you drove. An automatic car may not have that issue, but you're driving a stick, too.

In the end, I decided it was too harsh for my 99% street car, but would be awesome in a real 50/50 or track-only car. Even better for an off-road truck with an auto trans.
