My presta gauge is 5 psi different from my pump. I'm not sure which one is accurate. The air volume of the tires is so low that by the time I pump it up, remove the head, test the pressure with the gauge, then replace the head, I could have easily have lost 10 PSI, so making a direct comparison is... hard. Unless I make a tube with two presta valves in it.
