In the large auction house a powerbox for the V10 was offered. 45 Euro plus shipping. +30PS/50 Nm max. are clearly the tuning measures, which are carried out during the change of the software by well-known tuners (MTM, B&B etc.). There are usually +50PS/100 Nm. Quotation: Effect and functioning: The TDI motors of VAG can be tuned relatively easily electronically by increasing the injection amount slightly. The limit is specified by maximum Russian output and is at our In the cylinders, even at full load, there is still an enormous excess air which is sufficient to process an increased injection quantity. Torque and power increase until this excess air is consumed. Since the flow rate of the injection pump is specified, the required injection quantity is simply adjusted by means of extended control times of the injection valves. This is done by our external power box which optimizes the sensor signals That the on-board computer simply regulates an increased injection quantity. In other processes like the engine parameters is not intervened and all relevant engine parameters like e.g. charging pressure remain standard. Less power is definitely because the charging pressure is not increased. I bought the part and will test it once. At Porsche in Neuss is an all-wheel test stand. Let’s see what the small box really brings. Manufacturer is the company MAL Ele ctronics GbR.
