It doesn't tell me what value to expect though The Citroen manual tells me it should be between 1-4 Bar at 2500rpm when cold Jag manual says minimum 7psi at idle above 2500RPM minimum 14.5psi maximum 58psi I'm getting 20psi (1.4bar) on idle and 50psi (3.4bar) when revved. when cold: 50-55psi idle over 60psi @2500rpm which is too much really, buts its only at cold
