HPi tested the apexi intake bell mouth (bolts onto the AFM instead of a filter) and reported gains..
cant remember exactly how much - could have been from not running a filter at all..
my 040 had this same banjo fitting on it
just unscrewed that from the end of the pump, then bought a check valve for around $50 from motorsport connections, which allowed me to run a speedflow fitting onto the fuel hose.
well only other option is a leak in the hosing only seen during boost conditions
as GT shortie said, check thew vacuum lines are not split and are hooked up correctly... ie without controller - straight from IC pipe or plenum direct to the actuator
check that its all connected from above the turbo ... if you have the heat shroud over it, remove that and check that the arm is still connected to the wastegate flap

mine leaks
but i only used the std nissan gasket..
was told by plazmaman, that you should be using a sealant along with the plenum gasket for proper sealing

under documents find the power FC FAQ
search for "How do I configure larger injectors?"
latency and correction need to be setup
if this is for an R33 gtst like your details say
then you dopnt have type a or B
those are for the R34 NEO engine
you have the std type .. your case S1 poncam
or the PRO cam which requires the change to the solid buckets
as shown on thier website
http://www.tomei-p.co.jp/_2003web-catalogu...2_cam_RB25.html
you need S1 since the S2 engine they refer to is for sept 97 and later model engines
N1 is direct replacement for all RB's
it has the elongated hole for the 10mm bolt
other than that if you choose not to use that 10mm bolt, all RB water pumps will work
my rb30 crank has the wear pattern like right hand crank in this pic

so looks like the wear is the same with rb30 oil pump as well, regardless of the smaller gear
