This is the area where I noticed the largest diff with the fp rewire mod--- a 4th or 5th gear pull, even if its very minor (highway driving) will shoot those suckers up in no time if you're not getting enough fuel. Interestingly enough, aluminum melts at 660ish C (1200ish F), meaning anyone who tells you "you are gonna melt your head" is a dumbass---> i'm not sure why nothign melts anyways, i do sustained drives (3hours between stops) with EGT's at around 780C and never have any problems (knock on wood)
