Ok just got car back from garage... A think am hitting fuel cut sometimes ( well that's what it feels like)
Only does it now and again! Am boosting round about 20psi. Over last month a have fitted turbo smart waste gate as a bought new zisco decat and external mani, as old external was fooked, running dastek unichip as management.

Any ideas lads

Old setup was custom mani external wastage plumbed in to decat, manifold cracked so bought a new zisco mani and decat old wastegate would not fit as it was a square type flange so bought new turbosmart ultragate 38mm wastegate, it's ment to have a bar spring in it

are you sure all the vacuums are set up right?only thin i can think of is the spring is 1.4 bar or the vacuums are set wrong allowing it to overboost to anything it wants

No Rory standard solenoid
On wastegate top port vented, bottom connected to a t-peace, there's a vacuum line going from turbo to t-peace, vaccum line going from other end off t-peace to standard solenoid port and other port vented

This was how my old setup was like
