Another theory is the exhaust cam timing isn't dead on. Gelbster I think you posted this else where. Can the following be done with the engine in the car? Does it need to be dropped a little or come all the way out (Bank 2 // 4-5-6 side)? I think I read the cam timing could be checked/adjusted in the car with Jake's tools but not the standard Porsche tools. About how many hours would a shop charge to do it?
"use the adjustment tool 9612 (NOT the lock tool 9634) to assess the alignment. Yes, use the silver and red tool! Also note that Jake recommends - slacken the 4 adjuster bolts, adjust the Exh cam with the silver+red tool, micro -adjust the crank to align the pin hole (TDC pin 9595). Yes, this is the opposite way round to what is often recommended. The reason is that the cams are difficult to rotate (22mm wrench?) - so fix that first. The crank is easy - so do that last."

There is also the possibility that the chain from the intake to the exhaust is misaligned by a tooth or two or that your chain tensioner or the actuator has failed. Danny at Silent Automotive in Austin could address either for you easy enough.
He's straight-up, honest to a fault, and very knowledgeable. His rates are very reasonable, IMHO.
