best tune for 2014 sierra 1500 5.3l

[SAKO79]

I currently have a bully dog gt tuner and I think it was a waste of money. I got it to adjust tire size and better fuel economy. The head unit freezes all the time. I thought it would give me quicker throttle response but it doesn't. I'm very disappointed with it.

 

 

What tune do u recommend

I just got my diablosport trinity in today. Installed the tune and the throttle response is definitely night and day with the flex tune. I liked the bully dog on my other truck because it was very customizable unless I just haven't found those settings yet on this one.

 

Anyone with one want to tell me how to adjust for tire size, gears, disable v4 mode, etc. or is all that done through a custom tune?

From everything i've read on here the two people seem to like are tunes from Blackbear or Diablew. Personally i'm gonna get a Blackbear tune once i get back home in a few months.

Had Lew tune my last two trucks and really enjoy working with him on the tune files and he really gets the most out of it for HP and fuel mileage.good luck with your tunes!

Can't go wrong with either Diablew or Black Bear. I plan on getting one after the holidays.

I just got my tune back from BlackBear and its like driving a completely new truck.
