Had 2 cases of low boost and poor gas mileage with no codes. Both were cured with IDM replacement. The IDM contains circuits which monitor the actual ignition. This controls spark advance which affects fuel economy and allowed turbo boost that affects acceleration. A malfunction should set codes P1312 and/or P1334 but in these cases did not set codes.
