Loss of Boost/Power

[Mike]

Hi All,
Recently i noticed my car wasn't boosting as it should and doesn't feel as quick
its got a 9mm bosch, no gov/ground lda + TD04 turbo.. It used to boost just over 2bar

But recently its only been able to get to 1.4/5 bar

Inbetween this i have messed around with the fuel pump but no matter what i do, i cant seem to get it over 1.5bar.. im sure ive made a total mess of the pump now.. so im gona put it back to as standard as possible tonight and start again..

But im just wondering if any of use know any other problems what could cause this?

Ive checked for boost leaks and im 100% sure there isn't any..

so other than the pump just being setup totally wrong.. i cant think of anything else what could be wrong.. unless the turbos slowly dieing?

Thanks in advance for all the help
Mike
