Price, I'd say somewhere near 200 to $300, at least thats what I think he said a while back ago. Now if your the tester thats not the case, it may be discounted or free. As far as gains go I guess you could see a few numbers result from a better spark but really I'm not too sure. I do know that you get better acceleration and better throttle response. Now if all goes well and they get a tester soon they could be up on the market as soon as next month. Maybe we can get enough people by that time for a group buy, I've never doen or been a part of a group buy but I can look into it if anybody's in. Also try calling them on Monday.
