Re: oil pressure
What else have you done to your car, the general order of things to upgrade are as follows:
intake
exhaust
chip/clutch <-- stock clutch won't last long at this point
gutted precats/new downpipes <-- gut them the same time you do your clutch much easier when tranny is out of car
test pipes
intercoolers
injectors
turbo upgrades
etc etc..

Re: oil pressure
Clutch, if you haven't done a clutch yet you are loosing power, the stock clutch is only rated to around 300hp, have you turned up the boost yet to 14psi? When you do your clutch will leave shortly after unless you are easy on it.. You have the boost controller, so go after the AFC also..
But since you haven't done a clutch go ahead and do this.. clutch, downpipes (Random Technology), then go find a local shop to fab you up some downpipes unless you don't mind spending 600$ on random tech's test pipes, they have cats which are free flowing so that'll help past inspections..
Once you get all that in and running.. get the AFC and go somewhere with a wideband 02 sensor and get your car tuned, the JWT ECU leaves some things left to be desired as it runs quite rich and you should be able to easily squeeze another 20 hp out of it with the fuel curve and still be very safe.
Good Luck!

Re: oil pressure
Here's another note:
Save up all your parts for when you clutch and do this all at once cause it's a pain in the *** to get to all this if you did it in several steps:
When you do your clutch do *ALL* of this, it will save you much time, cussing, and pain.
- clutch
- rear engine seal
- downpipes
- new 02 sensors
- test pipes
- throwout bearing/pilot bushing/shifter bushing
- rear main seal
I know this is a lot to do but changing all of this at once will set you on the right track.
