I just had it done yesterday and I am pleased with the low rpm grunt it added. As I drove home last night playing around with the new power I was thinking. How does the ECM automatically go back to "stock" settings. The reason I ask is that I was pleased with the MPG that I was getting stock and dont want that to change for the worse when the free trial expires. I guess what I am asking is the "Stock" program that the ECM returns to the trucks factory program or Bullydogs version of stock? Is there any difference? Thanks!

 

the factory program with no TSB's done is what it returns your truck to

 

Thanks. I have never had any TSB's done since it was new so I guess I'm still good then?
