Yeah, we've got a TT one in the headache, and have track tested it, the
car is a bit faster in the quarter with it in than without it. I know some
people say they have trouble with them, the splice into the harness on
ours fell apart, so it got rewired, perhaps that's the trouble they refer
to, but who knows. It's a small community, one vocal member can make or
break a product's reputation, and often you just have to try stuff to see
what it does for you I'd say. (so long as it isn't an expensive
experiment)
