For starters I would like to thank " THE TRANSPORTER " AKA Paul (678)910-7068. If you need your Sling moved anywhere this is your guy. Great price and great service. With that said my BEAST produced a 387rwhp dyno run in a room that was 95 degrees at the time. The run would have been 395 or better in a cooler environment. I want to thank Dave and Jeff for an outstanding build especially in the detail department it made my OCD manageable lol. A special thanks to Angie for putting up with my weekly requesting an update. DDM Works put together a first of its kind that if you want brute force and a bit of a loud exhaust just ask for the 400rwhp package . You will not be disappointed. "Thank you DDM Works you ROCK"
