The BMW 135I N54 is probably one of the most fun platforms we have worked with. Its twin turbo inline 6cyl engine produces great torque and fast spool in its stock form. With more room to work with, the simple ECU flash takes the 135I from a already nimble driving machine to a powerful wheel spinning vehicle. As tested on our own BMW 135I, we were able to gain quicker throttle response, increased torque, even faster turbo spool, and top end that pulls very hard to redline. Simple bolt on upgrades such as an exhaust, downpipes, intake, intercooler only make this E82 chassis that much quicker!

What are the benefits of VR Tuned?
#1 priority is our customer service to you!
Our tuning is used worldwide. We have powered vehicles of all types.
All ECU tunes can be reverted back to stock if necessary.
With the VR Tuned ECU Flash, basic bolt-on performance parts will not require a retune of your ECU.
Adding parts such as an exhaust, intake, plenum, pulley, will all adjust with the tune.
If you add higher octane fuel, the ECU will adjust accordingly.
We can tune cars worldwide including JDM, EU, Australian, and USA cars for different types of octane or environments.
Other custom enhancements are available if requested and applicable.
We test and dyno tune on our own cars to make sure what you get is safe, reliable, and gives you the results you want!
