So this tells you that you either have a huge leak somewhere...blockage somewhere, or the turbo is knackered.
History. Has it ever ran correctly, what lead to the problem ? Does it run or sound any different ? You say it makes 10psi, and only 10psi...does it spool as it should to this figure ?
More details, intake system, exhaust ?
