You will definitely be impressed with the performance gains of the SCT X3 tuner. Although SCT recommended Model 3015 with "pre-loaded" tunes, you can do much better with
Model 3000 with "custom" tunes. You will need to provide specific information about your Super Duty using the link below.
Cal Request - Vehicle Information
There are several people in the aftermarket who offer "custom" tunes for the SCT tuners. I'm sure that SCT didn't want to specify which person to contact as they are all SCT wholesale customers. That said, when it comes to gas engines, Mike at 5 Star Tuning has the best reputation for maximizing the economy, towing, and performance tune profiles, has excellent customer service, and very competitive pricing.
