I read somewhere that there is an OPF (pressure) recalibration in ISTA.
If i assume this function well, it may help to recalibrate the pressure characteristics after the end-muffler has changed (or when OPF is getting older and older). I will change my exhaust muffler with a custom built one and will give a try to this recalibration.
