How did you measure that ?
Was it the peak reading ?
Unless you can hold the pressure steady accurate for a period of time
you cant compare the values as both will update at different rates.
Do both read zero when the engine is switched off ?
If so, then its ok as you are implying a larger difference.
(0 psi is not actually 0 volts on the map sensor wire)
Simon,
I reset the peak data on the monitor. I then floored it in 4th until the needle got to 2 bar on my boost guage. I then checked peak data under MAP and it said 26.4 psi
I know my gauge reads 0 when engine is off. Never actually looked at he monitor though. Will check it out
