Hard to say mate to be honest you'd need to do it n have it dyno'd but id get it checked over n full diagnosis done first make sure it's up for more, better safe than sorry

I'd say that's the best bet. It's possibly just the actuators slacked off or possibly your boost gauge has a split in the pipe dropping the reading. But just incase they've dropped the boost for a reason get it checked. May be nothing wrong in which case get the boost whacked up

Will check the pipe going to the guage but it deffienately only sits above the 10mark, is there anyway of prooving it has the mines fitted? As I have no proof, but do have a rr with nearly 300bhp n doubt it would make that with just exhaust and fmic

Mines is usually a complete ECU swap, and has a gold sticker on the casing with black "MINES" logo on. You have to lift the passenger's footwell carpet up and remove the kickplate beneath... Then the ECU will be staring yo in the face.
I'd also rule out he actual gauge first by quickly swapping in a mate's known proper working one. If that one also only shows 11psi, then carry on troubleshooting with the rest of the boost control system's components...

Thing is, even now running 298bhp, your 380cc injectors (assuming they haven't been changed?!), will be near max IDC (injector duty cycle). I reckon you're already near the limits of them.
Really, your next step should be 440cc (or 550cc) injectors, ESL Live ECU/remap for around 320-340bhp on your exisitng TD05H 16g turbo.

Well, the OEM fitment should be a '05.
All JDM MY93-96 saloons had them (plus STI wagons too).
The TD04 was fitted to the JDM WRX wagons.
You need to defo confirm by checking turbo's embossed casting on the compressor cover...

If it has been changed to a '04, then your car's AFRs could be all over the place, what with the Prova and FMIC i.e. no bespoke remap bringing everything 'together'.
Also regardless of all that, the '04 will be pretty much at its limits - normally maxes at 270-290 on the std slanty TMIC. (But your Prova and FMIC is obviously helping make a tad more power...)

There'll be a body of cast embossed writing at the base of the 'silver' coloured compressor cover. At the very bottom it should either read "TD05H" or "TD04L"
This pic shows the turbo upside down - you can make out the "TD05H" at the bottom (top in pic) of the comp cover:-

If you feather the throttle (on and off, on and off, etc.) whilst there's at least some meaningful boost in the inlet tract, then the BOV might # pfsssst pfssst # lightly. (And obviously it should make a big # PFSSST # after closing the throttle or gearchanging after being on full boost).
But it obviously should be silent when accelerating with the throttle open.
So you don't necessarily have to be at max boost for the BOV to make some noise when the throttle plate is closed, after coming off boost. This is dictated, to a lesser or greater degree, by the PSI rating of the spring inside the BOV. Your's prob has quite a soft spring...
