I have an 02 lb7 with efi live tunes straight pipe and intake i am currently over 1000 miles from home in wyoming and the truck has been running extremely hot....around 230 on flat ground with an outside temp of 95 any uphill grades will put my gauge up to 250+ until i pull over. i have an edge insight that reads below about 10 degrees. my transmission has also been doing the same thing as the coolant temps...any long grades will almost redline the tranny temp. dexcool is full with no air leaks and looks clean in resovoir. any help is greatly appreciated!
