I have been a car nut all my life. I still have my first car, a 1956 Chevy Nomad, that I have owned for 45 years. Over the years I have had mostly 30's through 50's cars. I recently bought a 1970 Challenger resto mod touring car. It is a finished car with a Gen III 6.1 Hemi and a 45RFE transmission. I found this site when I was looking for information about the computer system to run this car. It has a street and performance pcm and harness. I know nothing about tuning a computer controlled system and I want to learn more about it.
