A good place to start.
As small turbos & FMIC go. I run VF-40 with RacerX FMIC. I hit almost 17psi at 2800rpm. This for me works very well on the street. Theirs no prefect turbo, some say, 18g is a good compromise, but if you're going to pay for fueling. Mite as well go 20g. Because we all now power is one down shift away.
