On the TBird site they are talking about a computer upgrade that Ford does to the 02 - 05 Tbirds. It supposedly makes a difference in how the car runs and the gas mileage, kinda like the Troyer programs. Ford just charges the hourly rate to do the upgrade. Has anyone heard if there is an upgrade for the 99-07 5.4 trucks?

 

News to me... I know Ford does Programmers for CAI kits on the Mustangs which are available through Ford's Performance catalog, but I haven't seen anything for the trucks.
