Hi guys, I need some voluntary help here on a simple DIY.
This morning I was fiddling around the engine bay and I found the original earth point on the car which is mounted to the gearbox mount. I open up the earth point and negative terminal. I saw that the earth point contact is not good because the mounting of the wart point is painted so took some sandpaper and sanded off a small area around the earth mounting point then I took a metal brush to brush the ring connector and clean the negative and positive terminals. Then I put back everything.

1st thing I notice after this is the throttle lag has reduced and my headlights still dim when the ac kicks in but just a short while only. Now I'm not sure what I did made the improvements could be placebo effect. So here I hope some members maybe could do the same ad I did and see if there is actually any improvement because I'm thinking if this simple DIY can work then add in the ular Oren by YAB then the effect will be more better.

It will be nice if a few can chip in and try this and see the result got or not

Drive to Seremban let him test drive

Good for you. Wish I'm rich enough to test some of your thing, but they're just too expansive for me.
