Brought my 2010 335i in for inlet/outlet install and couldn't be happier with the results! Turnaround time was fast and I was kept updated with the installation. Patrick even went above and beyond and checked out my turbos to see if they were healthy, which they were he said. Also he even stayed after hours to help flash tune my car. Driving the car for a week I noticed it drives much more smoother and of course is a lot more faster. I definitely would recommend this shop for bmw performance needs and can't wait to return to make my car faster!
