Default Help: Boost Falling Off and Leaning Out

Really need your help badly, my boost is falling off, EBC is set at 14psi, but when it hits at 14, it goes to 12 and stays still.

Also try to boost 11, but when i get 15, it leans out.

Would an Adjustable FPR help, and just raise the pressure?

where do you have your wastegate Td' off at? are all you chargepipe connections tight, also do you have any plugs screwed onto the compressor housing? check to see if all that is tight. also tell us where your w/g is td' off at.

i am using an internal gate, its t'd off from the fpr vacuum source.

i'll try to check the connections again, it pulls hard but boost does not stay on.

about the plugs on the compressor housing? it don't really get it...

is it safe to bump up base idle pressure to 80psi? cause i did and i felt better power all around.
