Very nice specs - can't wait to get mine

Those have to be rated at the crank. I'm getting like 180hp at the wheels with regular. and thats going through an automatic transmission.

I believe they are from the website.

Factory ratings are generally to the fly wheel.

How is there really any difference in power? Just because you change the octane ratings docent necessarily mean you are getting more air and fuel? Does the ecu read higher octane and change the map and/or boost? I'm pretty doubtful.
