Lambda system requires higher pressure and flow than the Euro system to operate optimally. There are many things different about the two.
(My) target spec for the -007 feeding a 400whp engine is 1400cc/30sec. This is with the FD turned up 10% at 100psi. If you are not achieving that number then the flow to the FD is compromised or the FD itself is compromised. If you test the pumps at the FD inlet you should get a number significantly higher as there is always a return flow to the fuel tank. The Euro FD can also support 400WHP when turned up, but that is it's limit.
