I understood what he said. All I'm saying is that 90% more crap at 200% of the price doesn't make it 90% better. The AEM EMS isn't all that great. Now I'm not saying that from experience but perception. The fastest DSMs don't use the AEM at least last time I checked. IIRC Shepherd is using ProEFI, Rau was using Motec and Kiggley is using Haltech.
