I have the same issues on/coming off the two-step.

I wish I could help you with your tune on your carb. I use a Holley TBI & have done some tuning to help with the situation & it paid off with some pretty good gains in the 60'.

When we 1st started with our new combo 2 years ago, TBI & a ProCharger. We had crappy 1.45 60's & we saw the O2 issues in the data logs.

While our TBI functions differently than a carb. I added fuel to the table while on the two-step. My 1st change got us 1.35 60's. We have continued to make changes in that area & have gotten into the 1.2x 60's.

Our data logs still show lean on the limiter & fat coming off. It has significantly improved both on & coming off the limiter. Still trying to work the issue.
