Ive only had the car a few months and has performance mods (need to check list) but my boost gauge has always climbed right up since ive had it and been on the throttle. however tonight it would only go to a quarter even on about 80% throttle which is a first. is there anything obvious i can check?

 

Check a boost pipe has not come off ,or maybe one has split

 

Bloody hell is that common for them to split will check tomorrow
