Got the car on the dyno at the NZHondas dyno day recently, the oscillation from the pressure relief valve trick is quite obvious in the dyno plot but the power delivery is heaps better than before. 170wkw by 3600-3700ishrpm:

Quite happy with the result :)

Have you thought about running a restrictor in the line to the relief valve to dampen the oscillations?

The oscillation is more to do with the sudden opening of the valve which I suspect it would do anyway, the valve stays open once it opens - its just that it slightly overshoots the mark, which I would rather have than not reaching full boost as the AVC-R cant be trusted to do more than hold it there.
