rb25det with gt40, would i need z32 afm?

If you are still using maf sensors then you will need the standard one or the z32 if you want upto around 500 bhp.

What ECU do you have?

stock ecu chiped by rsp to 320bhp

Stock ECU needs a AFM so your need a Z32, although it will be holding you back power wise.

he only wants 450bhp bruce even with that turbo. it will be soo laggy its unreal

i think you mean unless he's running an ECU that supports a MAF sensor (i.e HKS f-con) then he'll need the AFM which he will do with the RSP ecu but he'll also need to let them know before he gets it as they'll need to incorporate it into the settings for him too

thanks guys will call rsp to get the details on mapping the car

project scrap it's gone over budget so if any one is looking for gt40,manifold,downpipe,wastegate, pm me
