I got my car with 53k miles on it, 2012 Eco mt. The first thing was trying to find the right tuning company, and food intake and exhaust options. Looking at the promises of other companies and on the fly gimmicks, I almost went that route. After much brain picking and evaluating I went with a bnr. I received the handheld and out of the box, it needed an update from Jerry. He had it fixed within a half hour. I ran some logs and had no idea what I was doing. Not only did he remote in to my computer from 1300miles away, he downloaded my own crap for me, reviewed the files, and showed me how to do it the next time..
Update one was stupid, the car made diesel torque from a 1.4, insane. The next tune was a little smoother, and the current tune is so butter smooth, and it pulls forever. I drive 110 miles per day and see 50mpg on the highway all day long at 70mph. It's the best mod you can do, and the tuning service worth every penny.
I cannot not recommend this enough. My friend drove his dad's and mine back to back, and he didn't believe it was a stock turbo, bolt on intake and mp/dp, he swore it was gone through.
i can't say enough about jerry and bnr!
