What should i limit my boost to with my current setup?

[Birdoprey]

I just put a new motor in my car and i have around 500mi on it. Everything is looking good with it so far. I was wondering what i should limit my boost to until i can add a few more mods. Here is its specs:
.020 over 6 bolt
8.5:1 Ross pistons(.020" over)
eagle H-beams
stk crank
balance shafts removed
Cometic MLS head gasket w/ ARP head studs
Stk 1G head and cams
Ported 2G exhaust manifold
Small 16G turbo with ported wastegate
Stk 1G 02 housing(non ported)
Stk 1G down pipe
3" exhaust from right under oil pan all the way back
3" Cat
Stk LICP
Stk SMIC
2 1/2" UICP w/ stk 1G BOV
Stk Turbo intake
Hacked 1G MAF W/ K&N filter(no airbox)
N/A Throttlebody
Stk 450cc inj
AFPR
Re-wired stk 1G pump
MBC
Right now i've got the boost set to 12psi. It will ramp to almost 14 right away then it settles at 11-12psi and stays there. I have a 255lph Walbro that i'm gonna install this weekend. Can i run anymore boost safely?
I plan to add a better 02 housing and 2 1/2" down pipe in the near future. I also have a FMIC that i bought from clubmitsubishi but never got the piping so i'll have to wait to intall it til i can afford to build the piping myself. Also plan to run some 550 inj. as well as some type of fuel controller(Probably the new MAFT pro) coupled with a logger. Ultimate goal is to be around 300whp which i believe these mods will do.

Pistons and rods and you're only gona run a s16G?

I ran 16psi on s16G with stock injectors and the a/f was fine.

I think you'll be hard pressed to hit 300whp with that turbo unless you plan on building the head.

Well, there is a story behind my mix and match mods...
I was buying parts to make close to 400whp. I bought 660 injectors, rail, full ss lines from pump to AEM AFPR, DSM link, and other stuff. I paid a guy for a full 3" turbo back exhaust, MAFT and GM maf, 660 inj and 255 pump. Paid another guy for a ported Big 16G(was gonna run that til i got everything up and running as well as when i got comfy with the DSMlink). Also paid a guy for a switchable AWD tranny. NONE of these parts showed up. I took a very large hit to my pocketbook. I actually borrowed the $$$ to do these upgrades. Now i'm paying back that $$$ with no parts to show. I needed to get the car up and running so i sold alot of the parts so i could get a turbo, CV shafts, Brake rotors etc. My goals have been downsized.
The car seems to pull pretty good now and i wanna up the boost if possible. I will add the other parts as i can afford to get them, but that may be a little while. Just don't know how much i can run with the stk injectors.

Keep it below 15psi until you get a datalogger.

Keep it below 15psi until you get a datalogger.

Short, sweet to the point.
