Afpr!!
 

Hey just a quick one, I am running a lexus afm, venom 550cc injectors and a walbro fuel pump. Do I need to run a AFPR? Or will my factory ecu compensate for more fuel and boost. I am running 12 right now, but would like to run 15 or so.
Thanks

First step, TAKE OUT THE VENOM INJECTORS! Do not run the car again until you have them flow tested. I have heard VERY bad things about them. After you get them flow tested and by some miracle they come out being normal, it would be a good idea to get a fuel pressure regulator. A popular choice is the Aeromotive. Suprasport.com sells a kit for our cars.
