I have been thinking about buying some kind of boost fooler. I have been looking at both the Quadzilla boost fooler and the Fleece performance boost fooler. The quadzilla fooler is only $120.00 while the fleece fooler is almost $400.00. What is the difference between the two foolers? I have heard that the fleece offers a little extra horsepower when used with a programmer, what about the quadzilla? Tell me what you guys think about each of these boost foolers?
