hi just wondered if anyone could tell me whether these readings sound right.

when my car idles when warm at 1000 rpm the vaccum sits at 12.5 psi

when i rev the car and hold it agt 3000 revs the vaccum goes to 25 psi

the oil pressure sits just above zero when warm and when at 3000-4000 rpm it moves upto 3 on the guage

just wondered if these sound ok want the car running perfectly

i wouldnt trust the standard gauge mate hardly any work , and the ones that do im not sure how acurate they are

the boost guage is an sw one not the standard the oil pressure is standard but goingto et an after market one. do the vaccum and pressure readings sound ok though??

even a black hole doesn't have 25psi of vacuum, bin the gauge.

oil pressure hot should be 1 bar at 750rpm and over 3 bar at 4000rpm.

so does that mean my oil pressure is low or would you say the standard guages are crap what are most accurate guage to use?
