I got the PowerChip Gold 93 about three years ago... It did produce notable performance improvement, but read my extensive posts on the subject of "off the shelf" ECU tunes... The maps are identical and were generated by Bosch / Mercedes for routine tuning and maintenance of the engine... The difference between the PC 91 and 93 is the amount of timing advance of the tune-up...
