I'm still trying to figure what box to get, either the power puck or the edge ez. I was reading up on the puck and it increases the injection pressure. Some people complained that injectors got louder and it may have even damaged some injectors. My questions are, can the puck damage my stock injectors? Does the EZ modify injection pressure also? Is the power puck risky to use and will it make injectors louder than normal? Thanks.
