Hi

It would be great if everybody who runs the smaller pulley could state there boost so that we know what the expected values should be for the different pulleys.

Please state both the Zeitronix boost reading and the odb map sensor readings.

EC 61mm(max boost):

MAP = 201.4kpa = 29.21PSI - 14.65(ATM) = 14.56PSI

ZT2 boost sensor: 15.95PSI

As you can see my max boost is 15.95psi which is very low. I do have a problem with my map sensor which for some reason gives me low ATM value.

The ATM pressure should be 29.21-15.95 = 13.26psi which is very low. My diagnostic tool says that the ATM pressure is unreasnoble low. Maybe that is why I get low boost value.
I will get a new map sensor this week and will be back with new test result.

What difference do you between the map sensor and the Zt2 boost sensor?
