Had the Edge Juice/Attitude standard program on in February for about 6 weeks. Tried the Quad XZillaraider Race box while the Juice was in for HOT program. I have had the HOT Juice/Attitude back on since Tuesday. Both boxes work fine and basically provide in cab adjustable power levels that match the manufacture claims.
I like the Edge HOT Juice/Attitude better because of the Attitude monitor functions and the Juice is a timing and duration only box. The Quad does timing, duration and fuel pressure. I am planning on stacking a Edge EZ for fuel so I can have control of both fuel and timing/duration seperately. It also has a 180HP setting!
I am happy with the Edge Juice/Attitude, either box provide simple installation and very smooth driveable power. Just my . 02.
