What about the cobb Tune?.
Sorry if these questions have been asked before, i did my best trying to search.
I was going to wait until my warranty runs out before reflashing it but IF with the Cobb tune or ESS i'm able to revert everything back to stock and leave no traces of the flash perhaps i could do it now
EDIT: it seems the cobb tune doesn't work for 2009 models?. why is this?
