Hi all i have an issue with my defi's my boast gauges stays at 2 bars but tep and pressure works fine. When i fire her up they are to the start up and bk to zero but the boast then goes to 2 bars stays there and beeps : ( any1 else had this.

Also i recently had this car rebuilt and and in doing so i have now have some unused forged 2.5 pistons which i think are 98 mm if im correct. These were supplied to me with my new 2.5 engine from RCM but the guy who built it recommended cosworth . Dunno if any needs but if so get in touch.

Also im looking for a powder coated locally to do my wheels. Im near bath so somewhere locally ideally.

cheers

 

Trace the wiring back to the sender, check that it's not disconnected anywhere, or shorting to earth.
Also check that the sender vacuum to electrical box is securely mounted and connected corrrectly to vacuum.
