There is nothing there to buy, not much I can do on the site to find the book. Maybe it's because I'm on mobile? I'll check around on the interweb and see if I can find it. Thank you though.
Ok, if you go back to speedtalk and on the page that lists all the forums you click on the announcements tab.
Right at the top of that page is a button that says “limited supply of Don Terrell’s horsepower chain”.
click on that and the instructions to get one is there.
They are only 40 bucks right now. That’s a smoking deal.
