Not too sure how u would feel surges if u properly switched the ecu to the resistors rather than the electromagnetic clutch. My lights flicker a bit in 2wd mode and will usually show 3 lights more than 1 light. It's really a non issue since the signal is going to ground.

The vx feels different in 2wd and imo not in a good way. I prefer to drive the vx in normal mode and i use the 2wd option only for cv problems from trails or playing around.
