Hmmm dont think I would be using one of these for some reason!!!
looks like its made from lead and plastic!!

I heard they go well with the CRM AR Ignitech powervalve system

ill have you know my Ignitech is very nice!!
Once I replace the battery in my trailtech I will report on fuel per tank as this is the only way of comparing before and after performance of that!!
