the biggest advantage to adding intake and exhaust are not only hp gains but lower egt's.anytime you use canned tunes(ie edge,bullydog,etc,,,)you cant maximize the potential for tuning.they are written for simple plug and play.call cale at bts(brians truck shop)he can build you a 6 pos switch that will have 6 different programs.you can have them tailored specifically for your needs.dp also has great tunes,so does tony wildman.for optimum tuning hit jody(dp tuner) at a live tune session,he will ride with you and build programs just for you,given you better bring your wallet.thats my take on it,im sure others will chime in.
