Pretty much a one man show here also. I can do it on my own, but its always nice to have an extra hand. My brother and I are partners, but with his work schedule, it makes it tough for him to get as much time off work as I can get. A lot of the time when we go to a 3 day race I will be by myself on Friday, then he shows up on Saturday morning. I can load and unload the car without help, and pretty much set up pit on my own. I'm no help to ya with the N02 data stuff, but I got to believe that if you keep good data(log book)and get a good base line tune up, you can come up with a routine that you can do on your own without any help. I've always found it funny that my help would show up after all the hard work was done..lol
