boost problems (high boost)

[cuprawill]

hi there got a 2001 ibiza cupra, and for the past couple of days the boost seems to be getting higher, its standard apart from front mount cooler and open cone filter it has no map. it used to boost 7-8 then it went to 8-9 and now its boosting 10-11. and this keeps blowing my boost pipes off bought some t clamps to replace jubilee (not yet fitted) but i cant understand why it would be doing this any help appreciated thanks will.

overboosting, a friend had this recently and it was a loose nut on his actuator
