I won't be posting any dyno until I have everything squared away. Headers are in, but I still need to source the DISA manifold and when I get that I will be getting dyno tuned with Evolve. I'll post my graphs then, but the before will include the headers and DISA.
For what it's worth, my butt dyno is pretty acute, and it is a very noticeable difference from stock with the headers.
