just done install grounding with eric, good deal, result , noticeable smoothness on engine response, when air con n lights r on. It feel more comfortable to drive with during stop n go traffic, especially old iswara like mine. I think is worth for a try, cheers.

But now macam back to previous condition, not much different liao, why ah, because engine self adjust with the current flow....?

Drop by here again.....was given Eric installed grounding like 5 years ago....still running good....

my old saga LMST has eletric issue since i bought...always burn the bulbs, headlight or interior bulb. and battery just only last 1 year plus.

After added grounding, damn my headlight never burn...or any other bulb in my cars. And my battery can last 3 years....definatly not joking... strongly recommned to install especially for old proton car.... thumbs up.
