I just ordered a tune from Randy at FSWerks. Haven't received it yet but he seemed to know what he was talking about over the phone and hes answered both my emails within the same day. I got a very good deal on the Xcal3 with 2 tunes from him for $360 shipped.
I'll let you know what I think after I receive it and upload it.
Just bought the car bone stock and only has an AEM intake so far.
