Boost question

I have a 98 gst witha t-25 turbo its running at 13 pounds of boost is that the normal psi I should be running? I read somewhere that its supposed to be at 15psi.

I believe stock is 12-13psi. You could run a mbc and bump it up to 15psi. I dont know if the t-25 will push anything over that.

yea 15-16psi is max on a stock fuel setup, However, the t-25 can make around 20-21 if you really have a nice setup but if you do then there's no point in have a t-25 ;)
