Used a few different tunes and changing up the other parameters finding what works for me and my truck best
Response and spooling is much better than what was previously on it. I can't say what that is since no programmer came with the truck
No noticeable mileage gains yet. I'm only about 300 miles into using though so finding it will happen
Overall great product especially for what I paid
When Ray finishes his it will be far better
