I had a few questions

[ford20]

I was poking around your site looking at your headers for the 05-10 GT and was looking at the Dyno Sheet. I had some questions while looking at the Dyno Sheet. Are those results RWHP or at the flywheel? What kind of mods were on the car at the time of the dyno? Do you have any before and after results from the dyno run? I am just curious and thank you for your help ... Here is the picture of dyno sheet in case it helps
