Hmm. Those look like divided housings - is your manifold divided also?

Yep - that's more or less what I did (not that specific manifold though). It wasn't sure if a single wastegate could be made to perform similarly, or exactly how to do it. Probably if you have long tubes running to the wastegate there wouldn't be enough "crosstalk" between the two exhaust ports, but I don't know exactly what it would take so I just did 2 gates. Gave a nice improvement in response.
