I run 3.5 boost on 93 octane with no issues. No data to prove it but car feels stronger than it did at boot 3.0

My service advisor has no issue with the piggyback and as long as BMS is faster car I'll stick with it.

That being said if there is a major engine or mechanical issue for whatever reason I will remove it prior to service.

Also if there is any definitive data or evidence to prove Dinan is superior I would not hesitate paying extra for it and also for more "peace of mind"

An ECU tune or ECU clone we all agree is the best.
