Srt-68 Barracuda

Tone ring....Tone deaf....Tone Loc.

What the hell is all that stuff? Sensors on each side? What the hell do they do? Do I need one? Is it safe to use this technology on the streets? Why do I have a waxy build up?

Flux capacitors and ECU's and Toner cartridge's when will the madness stop!?

Please advise.
