Is the bailey DV worth the money or are there other solutions to solve my boost leakage problem?
Every time I shift it makes a horrible studered sound. Please help
Thanks

I replaced with Bailey valves recently and I have nothing but good results with the new valves. Power distribution is much smoother and more responsive. Also, it will help you retain residual boost across shifts. From the data I've seen, it's pretty clear that the stock valves result in boost spikes or compressor surge or both (especially when increasing boost via chips, etc).<ul><li><a href="https://www.audiworld.com/tech/eng16.shtml">Valve Test article - nice</a></li></ul>
