I selected ecoMax tuning to perform the remap of my BMW 335d M-Sport after doing extensive research online and I am very happy with my choice. I got exactly what I asked for and more. I was in conversation, via email, with Jonathan for some weeks prior to the work while he helped me decide exactly what to get done. I settled on the physical removal of the DPF and the delete of the EGR along with a stage 2 tune. The physical removal took slightly longer than anticipated on the day as it is slightly more involved on this car but Jonathan was happy to work well past his advertised hours to make sure not only the job got completed but that I was absolutely happy with the final results. As for those final results... so I've had the car back for over a week now and have managed to fully explore the updated character of the vehicle. While it was never lacking in power it is now almost mind blowing. The way it pulls in 4th gear from around 1200rpm to the red line is nothing short of astounding, almost supercar like performance from a family station wagon! Thanks Jonathan, the school runs have never produced so many smiles per gallon! :))
