depends on who's running the event... to run an NHRA sanctioned event you do have to have the kill switch. i don't believe the NHRA will be doing tunerfest, just like fast fridays. i've been to numerous fast fridays with the 240 and it's relocated with a battery try that has J hooks and wingnuts and a metal crossbar for a tiedown. it's very secure and that's all they've ever looked for.
