ok i always felt the same about this grounding stuff but i recently was reading a magazine, cant remember which one but they had an s2000 they were building so after each mod they did a dyno, they put one of these grounding kits on it from hks if i remember correctly maybe greddy, but anyways it picked up 3hp at the wheels! now no doubt it might have bad grounding from the factory in the way its built but 3 hp at the wheels dyno proven? that made me rethink knocking stuff like that as quick. now the turbonator or whatever the hell it is that is junk and dyno proven junk at that lol. oh and dont knock the dyson! i love mine to death! you woulkdnt believe the **** that thing picks up its awesome! and when i put my dyson on the dyno with the turbonator installed and 40 ground wires attached... jk
