Evening all, I'm new to the scooby world, just bought a 97 jap import wrx sti. I am wanting to fit a dumpvalve and I've read a few reviews that an atmospheric single valve can cause fuelling issues.
What I would like to know is would I be better going for a dual valve atmospheric one from say forge for example and would this type eliminate the fuelling probs or would a recirculating dumpvalve be better? However as this is my first ownership of a turbo'd car I am quite keen on having the whoosh noise which I probably wouldnt get with a recirculating valve???? Any help would be great as I am very much a turbo virgin
Cheers
Chris
