do you have a wide band yet? what all mods do you have? I deff think a custom tune should be done but agree with you that a 2-3 hour drive untuned could be bad. what type of scanning tools do you have? if you don't have a way to scan kr your basically driving blind. Id say step one make sure you have a scan tool, 2 if there is kr then i would suggest a canned tune that way you can safely make it to get tuned
