[FlaToUt-GST]

I am getting rdy to purchase a used big 16g with 15k miles on it for $400...i think this is a fairly good deal. How can i tell when i get it if it is really a big16g or not? Thanks!

Well i was reading a post somewhere yesterday about how a small 16g is actually more efficient (by like 4%) than a big 16g...althoug the big 16g flows more. So i'll just settle for the guy's word on it. Thanks for your replys!

I think the regular 16g is only more efficient at lower boost levels. Anything from like 18+ go with a big 16g. Also, the big 16g has alot better top end.

i guess thts good in the long run, buti wont be seeing 18+ psi in quite some time...i'll have a fp soon, but 550s afc etc wont be for awhile..o well! thanks for the insight tho.
