yep newish ones are all set to 300. a bit older and you may want to go up to 350 but very few will need 400, only if its like one of the first ever Evo classicsOriginally posted by Slim KW
300-400 depends how old it is aswell.
i'd be VERY surprised if you need 450 in there,Originally posted by dave rock n roll
I just picked up an evolution X autococker and was told that the
pressure should be running at around 450. I don't know how old
it is but it can't be more than 2 years. Any ideas?
