Worth every penny! I took my BMW 435d to the experts and got exactly what I wanted at a great price. I first saw their video on the Living Life Fast channel and then read their reviews, which confirmed that they are the go-to guys for tuning. They did a stage 2 remap with dyno, boosting the power to 402bhp and 808nm. They also upgraded the intercooler, removed the dpf with a downpipe, and did a stage 3 gearbox remap. The difference is impressive - the car now responds much better, pulls hard in every gear and the power is smooth and consistent. I even noticed some fuel savings! I also got an exhaust conversion with a dual exit, diffuser and upgraded tips, which completely changed the car's look and gave it a great sound when combined with the dpf delete. I want to give a big thanks to the amazing team at Ecomax for their excellent service.
