Why steel valve caps?Details. Steel tire valve caps. Transponder bracket. Set the shift light to 11,500 rpm and set the clock (don't really need it, but it's there, so why not). Put in a few litres of the fuel that I'm planning to use (nothing special, PetroCanada 94). Fiddled with the no-load part of the PowerCommander map a bit more. First scheduled practice day is 20 April at Shannonville.
