Just had a local customer pop in here at Vivid Racing to get a VR Tuned Tuning Box Kit installed on his brand new BMW M4. The 6cyl twin turbo is very impressive in its engineering, handling, and performance. We have already had the chance to dyno and drive several of these with nothing but success. Improved torque throughout the entire midrange, better throttle, stronger pull. As tested on our UK vehicle with 98ron the VR Tuned Tuning Box Kit gives your F80/F82 BMW M car a gain in power from 430bhp to 510bhp gaining you 80bhp (crank horsepower)! Peak torque went from 500nm to 630nm at the flywheel. On our USA BMW M4 we tested, the car gained huge amounts of torque from the start of our test at 2500rpm all the way to about 6000rpm. Our tests were run on a Mustang all wheel drive dyno in AWD mode to not affect traction control issues. The car had a consistant horsepower increase from 3000rpm to 6300rpm. Nearly 70ft/lbs of torque was gained at 4000rpm with peak horsepower gains of nearly 60 all wheel horsepower at 4400rpm. These are super simple to install with the instructions here. Check out the pics of our customers car below. Order the VR Tuned F80 F82 BMW M Tuning Box! Leave a Reply Cancel ReplyYou must be logged in to post a comment.
