440i, Port Meth, BM3 flex fuel, Vargas GC+
We recently had this sleeper of a build F36 440i in for our Williams Performance Port Meth Kit giving even fuel distribution across all the cylinders in the engine. Whilst in we also fitted the @protuningfreaks BM3 Flex Fuel Kit which is used to allow the owner to drive the car without having to worry about alcohol/petrol blend % in the fuel tank as it will adjust parameters accordingly. Fitted at the same time was the @coolingmistuk stage 2 meth kit allowing the driver to control the fluid delivery progressively throughout a desired range of boost. Too complete the job, a stealth tank was fitted along with @odintuned 99ron, 99+port meth and e60+port meth maps!
