There is countless of posts around here of those with or had the Dinan S2 that are experiencing this. Some are lucky not having the issue
No, Dinan will not FIX this as they are blaming it on new BMW software updates which is BOULDER DASH !
There are plenty of us running flash tunes like Dinan in which there is no oscillation.
It had nothing to do with the car's intake, plnty of people runing 17-18 PSI on stock air box with again no oscillation.
I am 99% sure it is an issue with the PID tables.
