Blower Surge

EFI.....purdy sure that will stop the blower surge. Have been told that part of the reason a roots blower will surge is due to the fact that some of the mixture is used to "lube" the teflon strip on the rotors resulting in a somewhat uneven fuel flow at lower engine speeds...guy that told me ran a roots blower for years....but he very well may have been blowing smoke...no pun intended...
