I see a lot of people posting about 5 star tunes. What gains are you seeing on the 6.8 Ford v-10? I have the 2v version in my Excursion. How easy is it to use and can you still use regular gas? Or do ...
5 star did cause a ping on my V-10 while towing in the mountains and I found out it was the fuel filter not allowing enough fuel flow, changed the fuel filter and its been great since than, it also made the 5 speed trans shift much better and no more screaming in the mountains.
Every V-10 with the 5 speed needs this upgrade, its worth every penny.
