Reloading a tune meaning to "refresh" the tune in your truck

[04cr450]

I know the title makes no sense.. Was talking to Mitch the other day and asked his opinon on this... Basically a friend of mine has a 6.4 with KEM tunes in it, and he informed me that he was told from KEM tunes in order to keep your tune "fresh" they recommend reloading your tune thats on your truck every 6 months or so give or take... Well after i spoke to Mitch about this my buddy reloaded his tune and he stated his truck felt more alive and more snap to the truck upon taking off, accelerating, all styles of driving it.. Thoughts?

I have noticed this but only if my trucks sits with the batteries out

I've noticed this in my truck too. It always pulls with very little throttle for the first couple days and then it's like the PCM dials it back and it gradually takes more and more throttle for the same acceleration.

So it may be a good practice to reload a tune when installing new batteries etc etc?

To be honest my srl tune i have not felt a difference in throttle accel etc, but with other tunes that have been on the truck come to think of it have seem to get lazy. Glad i brought this up as i have never heard of this procedure recommended..

well most of us. at least me drive their truck everyday like a normal person. and just use extra power everyonece and a while like freeway ramps and such. and i think the truck learns to that i can deferentially tell my tranny softens up alot.

I was told that tunes get "lazy". I've been running the SRL+ full fuel for months. I switched to SRL+ reduced fuel yesterday and i noticed a pretty big difference in acceleration.

THIS is what is happening "adaptive learning feature"...The PCM is relearning the driving conditions.
