Upgrade the MCX blowoff valve?

Ive had good luck with the mcx one 3 years now

I've been running a MCX one for almost 5000km with no issues.

the stock spring in the mcx kit for my nytro was way stiff and wasnt blowing of squat, well blowing off the snow from the filter while the turbo was barking. i shortend the stock spring and it worked much better but then it did start to hang open and was leaking boost. i tried wet sanding the cylinder and it would work for a bit then it would quit again. tried lube to that didnt work.
i ended up replacing it with a synapsis, which works well but is really heavy for a bov.

If when you lift the throttle the snow BLOWS off the filter.......your bov aint blow'n off! i dont know if it will break the turbo shaft or not but the throttle response is so much better with the bov working correctly.
