Does enabling VG-2 slow down the radar detection or scrambler? Does it affect the radar/laser scrambler?

Yes, it slows down detection. VG-2 sweeps just like a detector, so to search for VG-2 the detector must stop looking for radar and wait for it to complete its sweep. The amount of time is short – about 1/8th second. While the detector is sweeping, it is not looking for radar. With VG-2 off, we skip this cycle completely and continuously look for radar. It does not affect laser detection as we do this in parallel. There is no affect at all on scrambling.
