ipd will do it for free. They send you a kit to remove the ECU, you send it back with the ECU via overnight shipping, they flash it, overnight it back to you, you're car is out for about 3 days. Alternatively, you can give them $1000, they send you a new one, then you send them your old one and they refund your money upon receiving it. Seems like a good deal and the performance gains are quite nice too.

I haven't done it yet, but I hope to soon.
And by "hope to soon." I mean as soon as I get another Volvo :-( I miss that car! I totaled it two weeks to the day I got it.... Stupid.... :-(
