In 'The Day' I cannot tell you how many guys asked for Cummins Button changes, stingers, any way around the max RPM on engines. I would adjust or eliminate the Aneroid mechanism/adjustment on SOME engines, would even drill out the 'ball' and remove a few thou of shims on a PT throttle, would swap injector sizes for DD's and set the governor on old Macks a 'Taste' high but never would I give as noted "Billy Bigrigger": any form or fashion of bump ups.
