I have an old TIM027 boost gauge lying around from my old car. It's a budget gauge (about 30 quid worth) and the markings on the face don't look that precise. I was just wondering if anyone has any idea how acurate it's likely to be?

Even a lot of expensive ones are inaccurate. Most are within 1-2 PSI but that isn't much help!
