Viking headers dynotuned

As much as I like aspects of other headers, Paul, your visually seemless work is really top notch. I love that it looks like some crazy 1 piece deisgn, and super happy that someone finally validated the pipes and their output potential!
 
Very nice, great to see validation of what’s been long suspected, and very similar plot to CES and Reband. Can I ask, what was the base tune you started off with?

I played with a few because I couldn't get it right. I think this was the tune it was running before the dyno
