Just signed up because I need a bin file so I can try to fix the tune in my car. I had someone else do it, and it's not right. I don't know much about tuning, but I need to learn some things. I have a small hot rod shop in a very small town in north east Texas, there's no one around here that does tuning so I have to do it myself.

The car is a 1981 Chevy Malibu wagon with a 6.0 and 4l80e, full float 9" UMI control arms and viking coil overs all around. I tried to post a pic, but it wouldn't load.
