	With boost lowered appropriately, deselect Fake MAF and set the clamp point to something around where full boost is achieved. Again, datalog MAFRaw to determine this value. Then log both MAFComp and MAFSD. MAFComp is the MAF sensor reading after compensations have been applied to it from the MAF Compensation table. MAFSD is MAFComp after VE adjustments have been applied (as well as factoring in pressure if you have Use MAP selected). Both of these are calculated even when they’re not being used. Adjust the VE table until MAFSD replicates MAFComp. This process will effectively map out the volumetric efficiency of your setup.
