About five years ago I drove my '89 16v Jetta through Colorado into Utah (from Virginia) with a Mad River canoe on the Yakima roof rack. The engine was not happy going up up up. I remember that I dropped below 60mph a few times.
Now I have the v6 Jetta. I suppose the 1.8 turbos have no problem at
10K feet, but I wonder how the v6 would handle it. Does the 'chip' controller do any sensing of altitude for changing the fuel air mixtures in my 2003 GLI? How smart is the chip?
