Steeda tunes

So i was reading a thread earlier, and someone said something about pulling their datalogs and sending to steeda to fine-tune adjust the tune to get the most out of it. Is this true? Does anyone have any experience with it? And if so, was there any noticeable gain when the updated tune was loaded on the car?

Gus, feel free to chime in at any point

That said, i couldnt be happier with how my car is performing with my steeda tune. Great tunes, great customer service.
