Bumping this thread, because I also have a question on gearing/acceleration. My VX feels sluggish off the line, and though the engine feels like it's putting out the power, it feels like it's just not getting to the wheels. Seems to be fine at speed though, it's just up to about 35 mph that it really feels dog slow. Running 265/70r16's btw.

1. Is this normal for a VX?

2. How much am I going to kill my MPG if I upscale the gearing?
