Is the grounding kit a crock? It claims to increase torque and Hp by making the computer systems in the car function more efficently. What do you guys think? Anyone have this?

 

Seems like a popular mod, atleast in the G35 forums.

It would be interesting to know the facts, dyno before and aft.

 

its cheap and its gotta be as easy as unscrewing some bolts and tightening them back down, right?

 

yes... I am unsure about the Stillen one, but the one I have read about uses 4 cables I believe,

1 Neg terminal to frame*
2 Piece of engine to frame*
3 I believe another part of the engine to the frame*
4 Trannie to frame*

* The instructions told you exactly which bolts to hook the cables to.

 

Too good to be true as far as an actual Hp gain I think

 

It'll definitely help the electrical system, but as for horsepower gains I would think not.
