Found this on the good old eBay!
BMW E36 320i E34 520i M50B20 chip Dyno-made 168HP 213NM with/out Vanos | eBay
Does anyone know if this would be worthwhile? As far as I can tell it's simply a case of opening up the ECU and swapping the standard chip with the new one, so installation looks a piece of piss, but is it really worth it?
I know absolutely nothing about how the chips work but obviously I don't want to destroy my engine, however a few more ponies and a little more torque would be sweet!
