New Member. GREAT to be Aboard. Just purchased 04 Excursion with 26,000 miles. Have several questions looking to improve MPG and HP
1-Just noticing so many "Chip Programing" manufacturers, makes and models. Which one is the best?
2- Once purchased do you have to have programed. I noticed in magazine companies like "DJ'S Tunes". If have to a programed by outside source which is best company?
3- Last but not least. My engine is still under warranty. Installing the above mentioned items, will this void my warranty?
As my first vechicle diesel, would appreciate the come back.
