2nd Jan 15 Hello Andrew, Cheers for the Tuning Box today on the F10 535d 313PS. I had a great 132 mile trip home. Made someone in an S registered 328i look like a right ****. Its on map 2+2 at the moment. I can definitely feel it pick up much better, at 80 it just lurches forward. It didn’t hang around before but my god it flies now, i will be trying map 3+2 tomorrow and see how that runs. I know i have asked you a lot of questions in the past about the box but now i have finally got enough courage to come and get one and wish i would of done a lot earlier to be honest. I wanted to drive up just to see how you fit and how it exactly works. I could only make it because i am off work at the moment for Christmas and i enjoyed the run out up to Durham too. Your team are a bunch of amazing friendly people and have the best of efforts to explain the box to me which i thought was brilliant. On the way back i decided to have a mpg test but not for long as i couldn’t resist not using all the power ! 😉 I got 55mpg over average of 70mph. I will be doing a review on here within the next week or so and recommending people for this utterly brilliant device you sold me. Dont forget to put them photographs of my car on your Facebook Page. Thanks Again Very good, i hope you have had a good christmas & new year ! Yep i am running 3+3 and its runs perfect, i was expecting an engine light but nope, it pulls like a train and that torque will be killing them back tyres ! :p Cheers
