thanks mark i guess i have to find out what build is currently involved now so i can download the correct software

With Holley, it's not a bad idea to have several software versions in your laptop. That way, when the latest version doesn't work right, you can back date easily and restore previous working tunes.

I use V4 on my TD car with a Dominator. Most of the new versions are to cover the various ignition setups of the Hemis, Coyotes and LS using stock sensors.
