What kind of engine management are you turbo guyz running out there? Reprogrammed ECU's? Electromotive? SDS? I'm thinking of going with the Simple Digital Systems. Anybody know much about this? And which one would be the best? EM-3D/EM-3E/EM-3E*
triggers Multispark/EM-3F? I'm thinking of going with the EM-3F.
