Hey John,
The tuners we offer are a good start to getting you where you want to be but a professional tune would be the safest option to get the most out of your F-550. Have you already added any aftermarket power mods or is the truck all still factory? Certain mods can have compatibility issues with the tuner so you'd want to check compatibility before purchase. There can also be issues with
I've used a few Edge tuners with my Silverado and mostly stayed with the factory tunes they have preloaded. I preferred the larger screen and functionality of the CTS3 # EP96TR over the other models. With this you could use the preloaded tune or make your own specific tune, but you really need to know what you're doing if go that route because you can easily damage your vehicle if you set the parameters too far from stock.

Hey John, how did things go with the Edge tuner for your F-550? Did the preloaded tunes help with the slow takeoff you mentioned? Your update could make it easier for others trying to boost performance on similar trucks.
