Rexperts.

Have spoken to Joe about this and want a little advise before pulling the cooler off.

After doing a few searches I think its either a split pipe or a faulty BOV.

Just fitted a boost gauge (have checked and its working 100%)

Car is making no vacuum between turbo and throttle body.

Driving normally i start to accelerate boost climbs to 0.4 bar as soon as it reaches 0.4 the boost drops to 0.15 bar. then when i get off the gas (BOV goes off) boost spikes to 0.5 bar.

car has power FC set to about 1.3 bar so its not ECU related.

thanks guys. All help appreciated.
