O.K. This might be a real obvious question but .... What the heck is a re flash and what does it do for your truck? As Forrset Gump would say " I'm not a smart man"

 

a re flash reprograms your trucks computer .

 

What he said.. It is just like updating software on your P.C.

 

It is often used on these forums as a term relative to reprogramming the various performance downloaders &/or the trucks oem computer. In particular the performance downloaders are always enhancing their programs to perform better or to be more user/truck friendly,.... hence reflash!

 

A reflash is when Jack opens his rain coat at a party twice.
