Rich again awesome article,in regards to the shift kit,would consult with LMS if they are aware of the kit and there knowledge and if the tunes are compatible and even better yet benefit to having an adjusted tune primarily for the kit,this is only my opinion to safguard the trans because it already has firmer shifting points,or does the tune adjust its own parameters,LMS also makes modified trans for the stang,so basically would consult with them before making the purchase,only my opinion.
