Fitted a boost gauge a couple of weekends ago and its not reading correctly, for example.... i now have my standard tte pulley....0.3 bar

when i boot it from arround 40 in 4th the gauge pings up to 0.3 then slowly through out the rev range decreases to 0.

doesnt matter what gear etc the gauge always pulls back to zero

any help?

I'd say a leak, as you get more pressure and flow its forcing a gap for the air to leak from.
