Thank you for your input! I have been contemplating upgrading my ignition as I am currently running a 6AL. However, I have heard some real horror stories with some of the digital stuff and was not going to change something that was working.

I think there is a Sportsman Racepak in my future. What sensors do you consider to be critical.

Thanx 451 Guy
