Sandals Posted May 26, 2018 Share Posted May 26, 2018 Check the intake for any boost leaks Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted May 27, 2018 Share Posted May 27, 2018 Could do with some more information. Does it do it at particular times? What car is it? Quote Link to comment Share on other sites More sharing options...

andyx187 Posted May 30, 2018 Author Share Posted May 30, 2018 It happens on and off readings are on pod gauge it is a 2003 wrx estate Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
DaveRAC Posted May 30, 2018 Share Posted May 30, 2018 Could possibly be the boost controller in the ECU if no aftermarket boost controller fitted Quote Link to comment Share on other sites More sharing options...
DaveRAC Posted May 30, 2018 Share Posted May 30, 2018 Could be a sensor getting an incorrect reading somewhere causing the ECU to cut boost down Quote Link to comment Share on other sites More sharing options...
Sandals Posted May 30, 2018 Share Posted May 30, 2018 Or a sticky actuator Quote Link to comment Share on other sites More sharing options...
