ASTROJET HOMEPAGE
Well I found the above and a few other sites where people had problems with them. I'd never heard of it before.. I think you'd be better off with a MSD ignition/coil/cap setup though that surely would be much more pricey.
My personal feelings- try it out. you've already bought it so if you like it- cool. but usu. if someone has to try real hard to sell you something or showoff on a 'performance part' (esp. if they are at a county fair) then chances are you're living an infomercial.
Just cause they say it- doesn't make it true. If it worked as well as they say it did you could probably find it just about anywhere..
My 2 cents
good luck
