Yes you can do it just like that I have the same thing with AMS 35R with same coupler and I had my car tunned on race gas but it was a street tune 25-26lbs for now since its very cold outside here in Chicago. 520 is easily reachable with all supporting mods my buddy's car made 520 stock Ecu stock motor. Once summer comes I will install and tune on my AEM along with a motor build
