Maft pro + Ultimate? I would just get the AEM EMS . The price you are going to pay for AEM boost guage its better to buy the TRU + the external sensor to run more than 20psi. And the you can hook up the TRU Boost and Uego to the AEM EMS so you can log all those things together on one unit. You can also ditch the knock box if you go this route. I hope anything goes well with your build. Take plenty of pictures.
