greddy e manage is underrated. it has the capability to "see" boost with the pressure sensor and you can tune it very well. Even though it is an piggyback computer, it has many capabilities. This system is used widely by WRX and EVO's that cant use hondata or dont want to spend the grand or so on AEM. I have heard many good reviews and good things about the Emanage from people that got the system and got it tuned. for example, one thing that the system is capable of is you can input your original injector size and then if you are running larger injector size you can input that and the emanage remaps your ecu to run with those injectors. it idles very well. its by no means better than the Hondata, but if you are OBD2 and dont want to do a costly conversion, then this is a good choice, everything you need should be under 400.
