This is the info on the receipt
On the receipt they called it PCM upgrade TSB 011203.
Under the hood it is labeled as
1R3A 12A650-AC
Change authority #02301.
The change is to address some pinging on initial throttle tip-in which was louder on the early production Bullitts.
The dealer wants to hear you say that it pings when you firs step on the gas.
