I've found mods are free when you have a good mechanic for a friend and even then theres a trade off somewhere.That cable is to close 2 valves(in the pipe)for better midrange,midrange is not needed at the drag strip.In the meantime;
Change your gearing-cheap,highly beneficial,go 520 with an aluminum rr,saves over 2 lbs of drive weight.
Race gas-not so cheap but if only used to drag race goes a long way-requires power commander to re-map.
Lower it.Frt and back.
Check E-Bay for a full pipe,and anything for that matter.
Remove unneccessary weight,lights,mirrors,rr peg brackets,horn,signals.

Sorry if some of this sounds basic to you,don't know what you've done already.
