I have to say that even with all the extra mods on the AWD 3rd, 4th and 5th are just as fast if not faster in the FWD I think. Of course that's on pump gas at 20 psi. Throw some race gas in and bump the AWD to 25 psi and she'll out pull the FWD no problem since the small 16G on the FWD can't do more then 20 psi to redline.

So there really is a big difference in mods vs performance on the hiway. I was suprised by how much.
