I need help installing a juice with attitude on a 99, the truck already has an EZ with digital gauges I'm thinking that you should be able to just take those hookups and plug them into the edge setup but I'm not sure. Honestly this is my first time ever installing a chip, and I only know that the pyro stuff is done and the boost, my brother is the one with the brains, and he's gone so I took over his TDR account,and he isn't here to help or do it himself, and it's a good chance for me to finally learn how. It is one of my friends trucks so if he wants to stack it with the ez is it possible and if so how would I go about doing it. Any suggestions would be greatly appreciated. Thanks
