Boost gauge tested good with shop air and a pressure regulator. I'll go a couple steps colder on the plugs. As far as the lumps go are they needed on a turbo engine? I would have to open up the center hole a bunch to use a stud and 1/2 inch nut instead of the bolt. I haven't used the water/methanol yet. I thought at low boost it wasn't need but I will turn it on at the next race. I have two nozzles on two pressure switches. Now one is adjusted to come on at 5 lbs and the second one at 10 lbs. I don't street drive it, it lives on a trailer. Thanks for the help.
