Right now im looking at getting a ems and I wanted to see what people thought would be best for my goals. I was looking at getting the rtek 2.0 but then i started looking at the Microtech ones and I dont really know which would be best for me. Im looking to get about 300-330 at the wheels my mods are an s4 street ported motor with a s5 bnr stage 2 turbo a cooling mist water injection kit and im thinking about using rc 750 secondarily injectors and a walbro 255 pump.
