For a 4.6is, Powerchip claims around 27hp/20ft lbs torque and other 'driveability' changes.
I am not promoting Powerchip, I am trying to compare what you are bragging about here to Powerchip's offer.
Thanks.

Whoa I never knew that? I literally went with what I saw on the Powerchip website..unless things have changed:
"Your
BMW X5 E53 4.4i Valvetronic utilizes a Surface Mount Chip (SMT) – a very sophisticated and powerful memory device which is fitted to many late model (post 1996) vehicles. Because of its complexity, the SMT style chip must be 'flash' programmed in the same way as the dealership (don't worry - we do this for you when we recieve your ECU), similarly to when servicing the vehicle. The ECU itself is very easy to remove, and should be sent overnight to be modified at Powerchip and then return overnight to you (we use FedEx Priority Overnight Service). Detailed instructions (including photos) are also provided to ensure the ECU can be removed easily from the vehicle. Once complete, and re-installed into the vehicle, you are back on the road to enjoy your enhanced performance – as soon as possible."
Anyway, P-chip advertises gains for $990. The highest price (and most common price, lol) in the email I got from SI is $649 if that helps any. I guess that's not including the overnight cost for the us :\ but still.
