Only used for about a month, in perfect working condition, payed $550 for everything shown great for supercharged and high compression all motor cars. Safegaurd ,once setup, cuts out spark when it senses detonation to not only prevent engine damage but allow driver to continue operating the car without worrying about damaging anything.
asking $400 but make an offer.

 

would you consider just selling the display
