I did around a 400 mile trip one way then back for another 400 which included steep grades and I didn't have a issue with my agp tt kit (even still got 22 mpg going up all the hills) I watched the engine temp and oil Temp and they never raised above normal, I actually think my grand prix gxp a runs hotter than my camaro with the turbos, my only concern would be tires and speeding tickets
