SCT Livewrie information
Hey everybody, I am a new member of the site. I have a 2006 F-250 Lariat 4 door Powerstroke. I am considering purchasing a SCT Livewire tuner. The only mods I have now are a Volant intake and Silverline 4 inch turbo back exahust with dual outlets. Will this product make a significant performance increase? How about fuel efficiency? I heard that if you have a problem it doesn't leave any "fingerprints" in the computer for warranty work, is this true? Any information would be greatly appreciated. Thanks for all of the great posts I have read so far!
