You can buy the inTune, but it won't solve your problem. You either need to get a custom tune from Ted Jannetty or a dyno tune.
^^ This ...When you put LT headers on you always throw codes until tuned. One thing you will get with the tune besides getting rid of the codes are maximum gains from your headers. Get it tuned and enjoy!
