an ecu reflash or piggyback add on ecu always helps but for just an exaust or intake its not a must. if it will make you feel better just reset your ECU so it can relearn to your mods. its ability to do this is limited and even debated on here but it wouldnt hurt.
you can either disconnect your battery or do a search on here for the ecu reset steps
