Running 80mph on the flats it stays 800 to 900 degrees. It never got over 1250 degrees, seemed to be where it quit rising. I was pulling a 32' tandem dual flatbed, only had a couple thousand pounds on it, and had my welder hooked on behind that(before it came unhooked and rolled 10 times) it is a big diesel welder and a real heavy trailer, might wiegh 3500 plus. Empty with no trailer on the freeway it stays below 650 degrees easy! It really pulls good, I am amazed at the great low-end snap it has, stomp on it and it moves quick! I turned up the pump 1/2 turn, I get some black smoke, but not much. I am adding 200degrees to what my gauge is telling me, my probe is right behind the turbo, and I have always heard that it was 200 degrees off compared to a manifold location, if it is accurate there I only hit 1050 degrees, but I really don't know so I am not going to chance it. If anybody has any opinions on this let me know! One hill I went up I usually top out about 65 with my 6.4 hitting the bottom at 85, I ran out of diesel right at the bottom with the '94 and had to switch tanks real quick(what are the odds) and got down to 60 before it caught, when I hit the top I was going 62, gained 2mph where my 6.4 looses around 20mph. I wish I had not ran out of fuel so I could have got a better test. Tomorro I am going up some hills that I have records on every truck back to '98 with the same trailer I will be pulling tomarro, I will post some comparrisons tomarro night. If anybody has any tricks for lowering EGT's let me know!
