Your just matching your selections to offset drone.

100% with you there.I should have been more clear. If you have the vacuum line probs then you will DEFINITELY know your car is slower. It will literally feel like you have lost your turbos. If you just sort of "feel" it is a little bit slower then it is probably you hearing those low end bogging out sounds. I found this to be the case on my two Eisenmann systems even after fixing my vacuum line problems. It is almost that the car just "sounds" slower because you hear the noise at low end when you first touch the gas pedal.
