Code 54 after SAFC install

[Ozz89supra]

So I installed an SAFC on my 7mgte and now whenever I floor it it throws a CEL and its code 52. My car also feels like its down on power. My car also never threw this code before the install. Code 52 only seems to come up once my engine is warmed up too. Could it be my wiring or maybe its really knocking?? Thanks! :1zhelp:

Sorry its code 52 not 54
