I love my adrenaline, all ya'll said and more. The only problem I have with it is everyday, After work( not in the mornings,) I get in my truck and the pulse will not display anything, not even a backlight. If I get out pop the hood and unplugg the pulse CM and plug it in, it works great, or if I shut the truck off and start it back it works. Every time I test the red wire coming from the box I have 5 volts, I plug it back in and it works???????? Kinda frustrating, but with all the features you get like gauges and turbo timer, I dig it. Just have to get by a little connection problem or heat or something?? I don't know, maybe I'll figure it out one these days I got time to jack with it, the good thing the box still works without the monitor, the bad thing is no gauges.
