stock truck

[catman2]

The temp gauge moves but only half of what it did when I had my stock muffler. Today I cruised at eighty into a headwind with the outside ambient temperature at 70 degrees and it rose to the lower bracket bar right above the C. Thats as highest it goes now even when I get into it.

I'm by no means saying the dash temp. gauge is a subsitute for pyro gauges, I'm just saying my truck shifts and runs cooler and better than it ever has now that I did the intake and opened up the exhaust. It use to take almost the whole pedal to get it to eighty and now with a little toe action it jumps from 70 to 80 -85 effortlesly with peddle to spare. And wants to stay there. I'm sure it would go to 100 if I pressed it, something it hasn't done in ten years.

"it rose to the lower bracket bar right above the C."

That sounds more like it haha. I was thinking you had a bad dash gauge or bad coolant temp sensor.

When I had my stock exhaust and TS tuning, it was all my truck had to keep it at 100. Now I know I can get to 90 with plenty of engine left. Haven't been to 100 in a while. Last time I did that I was following another F350 from Alabama to Louisiana. We started out at 80 in Alabama, Mississippi went up to 90, and Louisiana we jumped up to 100.
