Once the AFM (barn door) is open, the voltage sent to the DME is the same, be it 13psi or 25psi boost.. AFM is maxed out.. This is why we convert all modified 951s to a MAF setup. A properly designed MAF will allow you to alter boost, and with the proper code the DME will capture it (more boost = more air flow) and will always calculate the correct fuel & timing..

Yeah, I could easily see how a MAF would be able to calculate total air flow but knew that the AFM couldn't.
Thanks for the confirmation.
