Hey all, I installed a grounding kit a couple of weeks back now, and can definitely recommend it to anyone who hasn't already done it. It has helped reduce chugging alot, and the throttle response is a bit more...responsive too. It helps the DBW quite some. I also changed the alternator to car body earth cable, which was looking rather sorry for itself and quite stiff. The cable kit I used is about 30% thicker than the factory stuff and is OFC too, which will help alot.
