Also, do you have a gutted precat, but the stock cat? That's the first time I've heard of someone gutting their precat. Works for me, I suppose.

And Dpasseto, if I understand you correctly, you're getting boost creep (not spike) to 14 psi with the stock cat? Spike happens at the turbo transition (~4500 rpms) for an instant, while creep happens at higher rpms and increases with rpm. Creep is much worse than spike.

Exactly, the boost slowly goes up to 14 and slowly comes back down to 10. It only does this if I'm under-revving a high gear and I go WOT. If I'm going up through the gears normally then it's fine. I'll keep an eye on it once I get the DP. Thanks
