So the weekend trip to Tucson went fine. I only have a stock gauge in the truck and it works but it would be nice to have a number to base this on. It ran about 1/8" lower then with all the stock belt and fan setup on this gauge. I had a temp gun with me and when I would stop in I would temp the block and it was under 200 deg at each stop. I pushed it hard on the high way and it didn't mind at all. So next step is to get the lines for the a/c done and try to stay cool this summer.
