No sales pitch, just that the early systems are limited by the early type injectors with the Green ones only flowing 270cc/min at 3 bar, hence the need to go to two of them on the 996 to keep up with the fuel requirement at wide open throttle. The later Pico injectors come with a wide variety of fuel flows at 3 bar of pressure. Brown band ones as used on 620s are 330cc/min and the Yellow band ones are 490cc/min. So can easily provide enough fuel without having to run the duty cycle to long putting reducing the load on the electronics. A 59M ECU is a lot smaller and lighter than a 1.6M or a P8 so suffers less from vibration and can be used with a newer harness.
My option if allowed would be 748R Injectors and throttle bodies with the restriction bored out, a 59M ECU programmed to suit and use a modified Monster 620 Harness
