What kind of EMS are you looking into?
Gonna give another shot at the Mugen reprogram setup I have now. If that doesn't work I was edging towards the AEM setup.
One thing I may be doing is changing out the fuel rail and the intake manifold because they are currently both stock. When I do that most likely I will go ahead and get some bigger injectors as well. Currently running 550s I believe but I am thinking of going 700 and dumb em down a bit.
