It's also possible you have an oversized pulley for the TS2+ kits by mistake. (The TS3 kit I think was set at 13 PSI, but needed different cams and aftermarket headers.)

I would want to fit the headers with the engine out, but before you do that you need to figure out if your existing CATs are bad. It would be a bit silly to replace them, only to find you had the same problem. (Overboosting)

Maybe consider sending the headers back to the manufacturer to have them checked?
Sorry I think i have confused you, By headers I mean the OEM Manifold. I have standard manifold then eisenmann mid section and muffler so if the cats are bad on my BMW manifold how would I know?
