At the moment yes. As I've also said before avoiding them has become a good best practice. The best way to think of those dips are as preknock. The DME intervenes by dropping advance before actual knock occurs. As I've said before in cases where it can't react fast enough or properly you definitely hear and feel detonation with this motor. On the JB4 tuning the next generation of map 5 will be monitoring the knock sensor signals directly as well.
