It's been awhile since these have been discussed, but I'll be putting about 25,000 miles/ year on my truck and I was hoping that it still might be possible to tune it to about 24mpg highway?

Classically, any sort of performance tuner question has been met with "Go with blackbear" or you won't actually change anything yada yada.

I haven't heard a ton about people using these with the 07-13 pickups 5.3 AFM.

If anyone has any input, please let me know!

(Btw, I don't have $800 to drop on blackbear)
