I'm still struggling to do everything possible to eliminate that vibrations.(10-24-2025, 01:00 PM)TheLegend Wrote: Hi guys, does anyone knows how the syncro/balance of the injectors can be made to a 2017 RS NA? The place on the injectors where the adjustment screws has to be is sealed with a ferm metal cap. Is sealed only for European models because of the EURO norms reasons and without being able to increase the fuel flow, or... all models are the same(sealed cap) with no possibility of syncro/tuning/balancing?
Not sure exactly what is meant by the sealed caps. The throttle body assembly is actually 2 twin-throat assemblies. There is no adjustment between the throttle bodies of 1 & 2, nor between 3 & 4, but there is adjustment between the left and right pairs. However, it is not a necessary adjustment unless it has been disassembled - you're more likely to do harm than good. Any tuning would be done through a Power Commander or equivalent.
As talking about Power Commander 6, as I understand this box isn't a simple plug & play device, it needs to be tuned/calibrated by a specialist so, another costs(not small)? Thank you for your answers!
