Someone priced me an edge evolution programmer for my 03 Silverado HD 6.0. Can anyone tell me if these programmers are any good?

 

Prgrammers are no good for their price. Look I to custo tunin from blackbear, Nelson, or Wheatley tuning.

 

i put a black bear tune in my 6.0 and its the best mod i ever bought hands down. Great price too.

 

Where did you see the biggest gains?

 

Across the board. No one spot is best

 

yeah it was everywhere. Not so much mpg, the 6.0 isnt made for mileage lol. But it woke the truck up. Best mod i ever did hands down and i highly recomend them, if i could give on more piece of advice tho, get the auto cal. I have the generic standard tune and wish i had the auto cal. But thats IMO
