I just saw that Roush only offers their phase 3 SC (675hp calibrated) to JUST manuals. So I guess I just assumed the automatics weren't build for much for HP than what the phase 2 SC's offer which is 625hp. Maybe I was wrong?
Yea I'm sure there's a different reason why they don't offer it for autos I've never looked into it but the 11+ auto are known to take a beating forsure! U will be more than fine with ur auto!
