The name says it all. I had one and I couldnt make it work. Installed it and my truck would not start so I forgot about it and i was going to sell it but I decided to call Edge once more. Long story short I had my buddy reflash my computer in my truck to an old revision and walaa the truck started with the chip installed. WOW, I tell ya, I only use level 3 but it has alot more power and my mileage has increased 1mpg so far and its only been 100 miles. Whats the next mod to do, Air filter or exhaust?

 

So are you saying that your old friend flashed the trucks computer to an older HEX file or something?
