Stock boost levels

[Bubba9110]

Ok so I've heard a few different things about the stock boost levels. First I've read that the 1G's are at 11psi stock on the 14b and that the 2G's are at 14psi on the T25. I've also read from users posting that the stock boost level for the 2G is at 10psi. So I'm wondering which of these is true. Also the T25 maxes out at 15psi correct? If so is there really any reason to use a boost controller to put it up to the 15osi if it's already at 14psi? I'm not sure how much of a difference one psi makes but it doesn't seem like it'd make a lot. If you guys could shed some light on this that'd be great. You've always been amazing help before so I don't doubt you guys on this one

heres ### i did in the past few months. kinda along the lines of ### ## talking bout. i got a 97 gst, put on my boost gauge(glowshift) and it reads 10 psi, put on my MBC(nxsmotorsports) up the boost to 14psi, w/smic, 3 inch cat-back exhaust. then...dyno at 184hp/197tq.

got my direct bolt-on fmic(cxracing) from ebay, mbc started messin up, boost leak in my exhaust manifold, boost kept shooting to 20+psi everytime i punch it.....so i take it to the shop. They fix my leak and install my Apexi Safc, they run my baseline @174.51hp/190.79tq couldnt turn down the boost so i tell em to take the mbc out and tune at stock psi which is 8.....and my numbers are:202.06hp/208.76tq @8psi.

hope this helps!

Oh and i payed $450 for my fmic, it includes direct bolt on piping, intercooler, and re-circulating bov. and $20 for my greddy intercooler sticker with carb number......yea i stay in cali!

Ok... not sure really how that'll help me much but thanks none the less. I'm not looking for a FMIC, personally I don't like them much. I want to stay SMIC just with hard IC pipes is all I'm asking about. I'm not going to be getting a bigger turbo anytime soon so I don't really need an FMIC because it'll slow spool time if i'm not mistaken... plus the SMIC should hold up for a while on most turbo applications not totally sure about that but I believe I've read that here.

i cant tell much of a difference in spool time after install of my fmic. but yes the smic will suffice for now if you dont plan on a bigger turbo as you said.
