that's the best question i've heard yet. i had them same question and could not find the answer anywhere. nothing i could find in the bosch dme manuals i have. it would make sense that they would, however indications are that they do not. perhaps they think that they are throwing enough fuel at it that it shouldn't matter (remember, the system is designed to deal with aging components - small vacuum leaks that have more impact at idle than at wot, tired injectors, etc. - not major intake modifications). buy you a beer if you can find the definitive answer to that one.
