Problem is still here. And it has an effect on the performance of the car.
I have some things in mind, but it's like grasping at straws. Things like redoing grounds, rewiring the main battery supply. I'll give that a try and hope for the best.

Move around your trunk ground for your battery, make sure you grind off paint when attached.
You say you relocated the battery, is your positive lead to the front like a 0 or 2 gauge? Is it a good quality cable?
