hi im new to land rovers and this forum

i have just bought a 200 tdi k reg 90

ive been reading alot about the fuel and turbo adjustments and thought id give it a go

iv adjusted both and now my turbos boosting and 1.1bar (15.9psi)

but it seems i am not getting enough fuel

im getting no smoke and when i put my foot down no matter how fast or what gear im in im getting max boost and not going any faster

there was a plastic washed under the diafram whats this???

ive tried a few things on the fuel and no luck

any one know whats going on or know my problem?
