I would be very tempted to use STBs. But in the end they were the main reason why I sold my P4SS because they are very cutting in the ear at low medium rpm when you have an LHD especially on long trips which we like to do. As a passenger in my car it was much smoother because the hood and engine are a barrier. So soundwise it‘s OK for a RHD.
Does VCT still work equally well with the other ECU and STBs on the Sigma?
