'06 RXP Full stage II With riva inline water strainer.

I installed Riva high flow hood directly to air charger,Installed new iridum plugs and upgraded SC clutch washers today. I'm getting a Temp code ( I think it's P1445) under WOT now. I did'nt hit grass,sand or mud and the screen was cleen on the strainer..
Is this fuel related?
