Default Down sizing my Turbo ...???

i been running my setup for awhile now.
I am considering buying a T3 .50/.48, and trying it out and see how well it runs.

from what i have gathered from reserarching, it should give be a quicker spool, and a more responsive car.

you might loose flow on the top end.

think about it.. when you're racing.. do you ever drop below 4000rpm ?

my .63/.60 spools late as hell, which i'm actually starting to like, i'm not even boosting driving around town and still get 32 mpg around town, but it kicks *** at the track.

naw man.. the reason why you are getting 32mpg is cause you're leaning the ---- out of your maps and trying to burn that motor up
