You won't know what you're doing with just a wide band, the final tune may be worth over 100 hp and needs hours of dyno time.
If I were starting with a blank sheet of paper and insisted on an L6 it would be a Barra and a lot of $$$.
But that's the question: do you want 1,000, or an L6?
A JY LS will do that with truck manifolds and a single turbo...
