if i buy a prv how exactly do you work out how to set it? i think you do it from your boost gauge but how do you know if its accurate and your setting it correctly?
only just got it a month ago. i spoke to someone when i got it and they said 17ish is about right. am i right in thinking that standard a boost gauge should read lower in 1st and 2nd cos of the limit thing? and with a chip it would be about the same?
