Hey fella's, I just noticed this the other day. On my stock setup my boost gauge reads 10 psi around 7k rpm. Passengers have told me I hit 10 but I'm too busy paying attention to the road to look. I figured it was just the angle they were seeing the gauge at. So I gunned it and looked myself, sure enough I hit 10psi right before i shift out. Do you think I am really hitting 10 psi or is the gauge reading wrong?
