The monsterous BMW M5 F10 4.4L twin turbo packs a nice 560bhp from the factory already. But tuning these cars to more wheel horsepower is easy with the addition of some parts. Our customer in Kuwait has beefed up his aesthically and performance wise with the addition of high flow cat downpipes, cold air intake, and now the VR Tuned Tuning Box for the BMW M5 F10. Running his car in RWD only, he gained a very strong 60rwhp and 60ft/lbs of torque on 91 octane with this plug and play tuning box. Watch the video of his car on the dyno here – BMW M5 F10 Tuning Box-Dyno Run. Like what you see? Order your VR Tuned BMW Tuning Box Kit Here.
