Thanks for the info.
I am aware that a tune will extract all of the power potential out of mods such as headers.
Was thinking of getting headers and then running un-tuned for awhile before getting a tune.
Never heard of permanent error codes before; that is crazy.
So to do things correctly, I would need to have a tuner turn off the error codes before any mods and tuning is done?
