Afternoon fellow BMW owners. (And those Porsche folk as well....!) As the kitchen/orangery extension removed any possibility of swapping the 320d for an M4, I’ve been contemplating getting the current car mapped. I’ve done this with previous cars, Saab 9-5/Alfa 159, with great results. I’m not keen on a generic map as these aren’t always specific to the car/gearbox etc. Nor am I keen on a plug in box as these simply cheat the ECU into adding more fuel/air. So I’ve been looking for a company who can do a custom map using a rolling road. Found these locally: http://www.p-torque.co.uk I’ve contacted them and the reply was: “We tune your BMW to 230hp and 450NM Your car will be set up on our dyno. We will then simulate road conditions, take data logs and build the ECU calibration accordingly. This is £345.00 and we allow approx 2.5 hours for the process. If you book a slot before the end of January and use coupon code PTXMAS2019, you will get 15% at the moment as we have our Xmas special offer on.” Sounds very tempting indeed. The ZF6 gearbox is good for this hike in power and torque, I’m now wondering about the intercooler/turbo and associated DPF nonsense. Will these take up the strain given that the car has 79K on the clock currently. And experience or thoughts most welcome. Before I take the plunge.... Thanks.
