Has anyone used either of these? I'm looking at getting one. I don't need a big HP box, since my stock clutch won't handle one. Oh ya, I have an '01 HO with 6 speed, if it matters.

 

Quadzilla is cheaper and offers a 90 day money back garuntee. It is also upgradable to add 70hp, which your stock clutch will handle pretty safely. Not to mention their customer support is outstanding.

Edge states theirs also adds horsepower but don't think they list how much. They make good products as well though, so not trying to tell anyone to stay away from them.

No experience with either, just some info I have gathered while searching the same topic...

 

I have the Quadzilla XZT+ and for the money you can't beat it. His customer service is second to none too. Plus, it has a USB port and he can do anything, I mean anything to it if you have any problems. Now he's trying to do a high idle for us. Pretty good company if you ask me.
