I have a huge library of Sun Tune Up Data sheets that I have inherited from my father’s auto repair business. I know for classic car buffs (myself included) – this data can be invaluable for keeping your car in tip top running condition.
I did a lot of research and found guys trying to sell them for $10-30 per sheet. My intention is to provide all of the data that I have here at no cost via a simple pdf view and/or download. I do generate a modest income with a Google Adsense account – please visit the advertisers to help keep the site maintained. I promise to keep the ads to a bare minimum, as well as no hidden popups or crazy web BS. Simple. Safe. Useful.
