If the 6758 will do near 500 rwhp in kill mode - then I'd be fine with it. I'm all about pushing a compressor to the max to get the best powerband possible. I don't really need a 550 rwhp turbo since I don't see the car ever having the fuel to do that on E85 or wanting to push the transmission I've got that hard.

But if the 7163 is the ticket to making above 450 rwhp, then that's obviously the way to go.
