Finished up this 2014 5.3 6l80e truck today. Dod turned off till it can get deleted and tuned. While tuning, I picked up .9 mpg with doing some wot pull. Fun clean truck. Getting your stock vehicle tuned is one of the best investments you can do as they pay for themselves. Better drivability, better mpg, more hp, last longer, and is more fun to drive.

A kinda rare 2013 6.0 silverado WT truck norris and exhaust came around for a tune as the previous tune was a mess, and the truck barely ran. It's much better now.

One thing I hear a lot is that stock vehicles don't need a tune or a tune won't help. Well, that is simply not true. Tuning a stock vehicle can help in many ways, like an increase in mpg, better performance and feel overall, and even longer engine and trans life. A tune will always pay for itself.
This trailblazer went from 14.6 mpg hwy to 20.6 hwy, with more positive transmission shifts and feel, less knock, more power, and it will have longer engine and trans life on low octane fuel.
