The new 435I coupe with its N55 turbo engine is pretty strong and sexy. But take the 335I sedan, give it some more styling to the body and you have the 435I GranCoupe. Still powered by the N55 turbo engine making 306ps, it gives you 4 seats for the entire family to ride. We had the pleasure of this one swinging by the Vivid Racing shop in Gilbert, Arizona to have one of our VR Tuned Tuning Box Kits installed. The simple installation takes about 30 minutes as we have dyno tested on a F30 335I, it makes 61HP over stock. Using these Tuning Box kits on our own Project Vehicles such as the Mercedes CLA45 and the Porsche 991 Turbo just puts the credit that these things are where it is at when it comes to new age turbo tuning.
