15 1/2 lbs

i just installed that blow off and now im running about 15 1/2- 16 psi on stock turbo should i back it off or should i be ok

Should be fine though I'd worry more about the feul delivery than running the stock turbo too high and possibly even the cooling system.

Ya he's correct. I'd be concerned with fuel delivery right now. If you're noticing fuel cut, rich/lean conditions or CEL lights, I think it would be time to turn it down to 14lbs.

alright, right now its running better than ever, i havent noticed anyhting yet but if i do ill turn it down to 14, thanks a lot

I wouldn't stretch it like that. You MAY do more damage by running it as is. I'd tone down the fuel before you do damage to the engine even though it's running the best it ever has.

buy a 190lph for $90and you can run the stock turbo on 16lbs safely. And dont buy a 255lph pump either.
I dont know where you live but what octane gas do you have? 15.5lbs will be safe now if you have 93, but out in cali we only have 91 and that would be pushing it.

yeah i live in new jersey, the octane is 93

Well then you should be good as long as your injectors and fuel pump are powerful enough to keep up with the demand and the computer is set up to support the boost.

time to get a high fuel pressure regulator....

Yep I'd say so

NOT time to get a fuel pressure regulator. They have their place but they only complicate things and are not needed/should be avoided until you are making so much power that you need a 255lph fuel pump. I am running 20-22psi on a big 16g turbo with 680cc injectors and a 190lph fuel pump and the stock fuel pressure regulator is just fine.

a lot of people have told me not to put cams in my gs which is a idea but if i am trying to make a high compression all motor car "N/A" i have been told to get bigger cams. would i need a bigger fuel pump as well?

I would say no. Cams arent going to need THAT much more fuel. What you really should do, is get an SAFC and take it to a dyno to tune it. With bigger cams you will be moving more air/fuel into the engine. Tuning will get it to run better and give you more power.

now i am overhauling the motor. boaring it out .25 bigger pistons new hardened rods and so on. i alreay posted this but with the overhaul of the head and the bigger pistons all that fun stuff i should be fine with the stock pump right.
