I bet if you lean it out to get it to the same AFR you were at before, you'll see some gains.

Yes. He's still on the stock turbo.

Yup, that's the plan. He didn't get retuned for that dyno run because we still have an intake manifold and throttle body to put on. We also just wanted to see what the raw gains were. I'm sure once everything is swapped and tuned properly, we'll see some nice gains throughout the power band.
