Marco,
Saw your message asking about tunes for early NA cars. Yes, I have quite the stockpile. However I just want to forewarn you that tunes from other people should be treated ONLY as base maps, it will need adjustment to suit your particular car. The maps are tailored to my car, which has a cam advance key, an Elgin cam, and some head work. They will start your car but will need tweaking to be a good fit due to these mods I have. Also, the tune file itself will need to have every property inspected. Your spark angle offset will be different, as will most of the injector and coil settings. My sensors may or may not be a match to what you are running so the calibrations may need to be redone. Just stuff like that. Keep us up to date on the progress, happy to help if you get stuck.
