Hi iv got a map on my golf pd130 mk4 for about 180bhp and on my boost gauge im getting about 28psi and iv been told that much is bad for turbo iv not got a lot of experience on changing things in a map and would some1 be able to tell me wot i change to drop the boost down to a safe limit as i dont really fancy spending out on a new turbo if things go pear shaped lol if needed i can upload the map
