Ecu reflash to exact exhaust. Dyno required?
I'm thinking of getting the yoshi rd77 3/4 system. I've seen online that schnitz racing will flash an ecu to this exact exhaust map and will be more cost efficent than a power commander/custom dyno tune. I know this is threaded on quite often but just wondering- will an ecu flash to an exact exhaust make the pc tune not needed? The woolich website made it seem like it is not needed but I just wanted to be sure. Thanks in advance
