Solo, first time doing it, it took me 3 hours from the time I shut down the truck to the time it fired again. Absolutely straight forward, no problems, fairly simple procedure. Out of the things I've done to my truck that I was worried about screwing something up, it's right behind drilling for the pyro and in front of cutting the tranny line for my temp gauge (which I don't have anymore). EDIT: Do still have the gauge, just put the line in with the port rather than running the temp manifold.
