sorry if this is in the wrong place i looked for other similar subjects and couldnt find anything similar except this tuning part. ok can you tell me how this works different than say e-manage? ( http://www.powertraincontrolso....html )i would like to learn more about the differences in these devices. i read some threads on the differences on e-manage versus AEM standalone. so ya now im interested in the ways these work thanks for your help
