I have bought a 410bhp jdm spec c with tuning by the scooby clinic but the car came with a turbosmart dump valve and I want to switch back back to oem but I think I might need an upgraded part due to too much turbo pressure. Any thoughts?

Standard OEM dump valve will be fine with 410bhp mate.....

I have a 340bhp sti uk that I was using for a week before getting remapped a few years ago after doing all the other mods myself which sounded like it was loosing pressure while in the short period of overboost. The reason for this post was that I was guessing it would not be spiking over the pressure of my bigger turbo on the scooby clinic car yet still leaking.

If I can get an oem for a fiver off ebay I will probably try that first otherwise any recomendations for an aftermarket recirc valve?

In my experience the oem leakage was quite subtle, the turbo was maintaining boost but working harder to do it and creating heat, I know this because I monitor turbo pre-intercooler temps.
Ok to try the oem item at little money but just don't assume it's safe at that level.
I use a Turbosmart plumbback re-circ which is around £270 but in my experience cheap at the money.
