hi folks!

when mark was mapping my car he commented on the boost gauge under reading compared to what the ECU was seeing.

when the car was on the rollers at AVA i mentioned it to allan and he compared it against the boost gauge they connect for the rollers.

it under reads by exactly 7psi.

after speaking to SPA technical about this they are convinced that its not the sensor or the gauge and in fact its reading the correct pressure as they have never ever had a faulty sensor

why on earth would it read under by 7psi??

any ideas??

going to try my mates sensor to see what happens....

cheers
