Some may have searched for hot chips, but honestly I would be surprised if they are out there.
Newish model, with fairly 'exclusive' sales volumes- hard to entice programmers unless they $ee a market.
Had the same issue with my Lincoln LS Sport 5 sp.
It will be tough to get to Mustang numbers, at least at the drive wheels- different layout of exhaust and drivetrain.
Plus, they may get more power than stock, but it will definitely be at the expense of gas mileage.
