We finally get to test out how fast this s300 Duramax is! On the last video of us trying this, things didn’t go as planned. We had some major fuel leaks almost instantly within the first few rips and didn’t get to really test out much. I had finally got it to stay together enough to do some good solid rips and burnouts! THIS TRUCK IS AN ANIMAL! I really like the s300 turbo and if you want to know how to do it to your LB7, I have a video on my channel of the full install and everything I needed to complete it!
