The p8 will need a pectel board or mod if not already done done an yes it will need to be re mapped to run the air injectors
I am pretty sure it does not need a "Pectel board" as said it's just an output so in theory a mapped ECU for the injectors should be suffice.
The "pectel board" most speak of is merely a form of hardware decryption to allow, Pectel software to run, nothing more.
There is another one that allows 12 pot boost etc.
^^ beat me to it lol.
