I finally fitted my autometer z series pyro and took the truck out last night, I guess the temp was just above freezing out. On start up from cold the gauge read around 250* after about 3 mins ideling which I guess is about right? but when I buried my foot in the floor the temp just touched 1300* for a split second. Does this sound right with the mods I have done? ... . The truck was empty& not towing.
