Has anyone stacked an Edge/Attitude and Quadzilla? Is it the same stacking these 2 units as it would be an Edge and Predator? I have found a few threads on stacking the Edge and Predator but not too much on the Quadzilla and Edge. I have an Edge/Attitude and am looking to add either the Predator or the Quadzilla but am looking for opinions!

bastard stack . . . been around for a long time. mtomac has used for quite a while. Works well. I have one . . . great.

Why do you call it a bastard stack?? Is it because no one really runs it or is it because there are problems with it?

don't know why . . has been around a long time and is the most common stack I have heard of. I am sure it works better on some than others. Once you start using tuners/chips there are a lot of other issues that have impact on how they work. If you don't have a tranny/clutch upgrade you don't need to be lookin for any other mods until that is done.
