I hear that. Good feeling just to hear it. I know for me I was just happy to know that it actually worked after spending all that time and money haha.
That's kinda the main reason I bought a Power Fc, I like how they include a fully functioning base map to start with which makes tuning a little less time consuming. If only it would replace the stupid maf with a map sensor, then I'd be one happy dude.
The ems is kick ass though, my budget didn't allow for it. I've heard great things about them though.
