A 'Live' demo where you take a normal running 351w or whatever- remove the original induction system- replace it with your system , wire it up-program it, whatever -run it, preferably on a dyno or on a test stand so that before/after results can be compared, and give a definite, final cost and show people just how simple it is. At the end of the day I believe that is what the real buyers want to know & expect. Obviously SEMA probably wont allow this indoors, but if you had an outdoor setup on a trailer etc where they could go watch the process say twice a day at specific times it might work.
