haha that is pretty sweet. If I was him and got toasted by a 6.5L, I would probably pull him over and shake his hand haha I keep trying to get my brother to have a little friendly race in his 24 valve but he needs a new clutch first. His is slipping. so I am just lying in wait haha And yeah, the GM-3 does get things pretty toasty under the hood. That intake sure heats up quick after a short burst. I did race my buddys 97 stock 7.3L in my truck when I had the GM-3 on it with mods, and beat him off the line enough to get a good distance between us but after that he didn't gain on me but I wasnt pulling away either. Still made me feel good that the old 6.5L can hold it own with a direct injected diesel with just a few simple cheap mods.
