Today’s customer wanted a little more power and MPG from his (well hers) Mercedes A Class, plus they also had an EGR issue that need sorting as well, seeing as we were the cheapest quote in the area an offer free EGR & DPF fixes if requested with our Stg1 custom tune he insisted to use us! With only a few days notice we got it booked in and sorted, power up from 170hp & 340nm to 210hp and 420nm although these do suffer with torque related issues once past standard, so we reset that as well, a lot of miles on this example but now with a lot more to come!
These engines are fairly easy to tune and respond well to a decent Stg1 remap, They basically run the same software as the twin turbo version of the same engine. Obviously these only have a single turbo but regards remapping it makes it much easier to see the restrictions put in place by Mercedes. I have had one of these engines myself and easily achieved 50+mpg even with the increase in performance, the best i ever saw was 70mpg on a not so long dual carriageway run. The engine was smoother and quieter as well.
