As I have mentioned more than once, my tow vehicle is a '94 Chevrolet K1500 6.5 turbo diesel with 3.74 gearing. In response to a thread started by someone about something, I made passing reference to a recent trip to Colorado/New Mexico and my dissatisfaction of the truck's towing capacity while in the mountains.

I need to explain.

It turns out I had a vacuum leak, as well as problems with the controler for the fuel pump. The mechanic says my wastegate was just staying wide open, giving me no boost, and the fuel mixture was mostly lousy anyway.

So, the bottom line is, I have no idea how one in proper tune can cope with towing at high altitude. For all I know, I could have passed everybody on the road. Ok, I do know better than that.
