I found out, calculated the vf39 to 435cfm & 32.4lbs/min. This gives me more than enough reason to justify installing my 16g w/ 580cfm/ 39lbs/min compresor wheel. Now I don't have to worry losing much mpg, or my spool time, and get some more ponies midrange and upper. I think it will give it just enough power to be where it should have been from the factory.

Next question is how much do the 06 STI fuel injectors flow?

The new WRX's are just over 550cc's right? I was going to install 660's w/ the wrx, so it make sense that I would install slightly bigger ones on the STI.? But i think I remember hearing that the 06 sti's had bigger injectors, but by how much? I can't find any of the info I was gathering when I was looking to buy it.

the stock usdm sti is 565cc same size as the 06 wrx as 565cc. which are good for up to 330-350 whp

yup

Do you think it would be wise to get those UR injectors since they seem to work well w/ my turbo? Even though I think I will only put down about 350 with all those mods I listed?

Also is the lightned pully actually worth it? Sorry for all the questions I have been searching and researching, but I trust the opinion of you guys very highly.

-P&P'd exhaust manifold (have)
-My Spearco TMIC w/ P&P'd elbows (have)
-perrin Y-pipe
-Perrin lightend pully (is it really worth it?) (Don't have)
-intake (have)
-TBE (have)
-Cobb AP ( protuned after installed)

It looks like they actually have them in stock. Although Gruppe-s sells them for less if they never have them available it doesn't do much good. There is also a guy selling his brand new set for $1250. Gotta search for his thread but I just saw it like yesterday.
