Myself and my Brother had our cars tuned by Enda yesterday, We are both pleased with the outcome.
After having the engine remapped, the acceleration is intoxicating. There is a noticeable 'thrust' as it spools up and gathers it's skirt.
After we had our cars tuned, we found a section of road where we could do an acceleration comparison, and the 330d and e320 were almost identical in performance.
On the way up to Birmingham I filled the car and reset the trip counter. When I arrived topped the tank and calculated the car returned 36.6 mpg. After receiving the new map we had a couple of runs to 'feel the difference', then had a race with my brother and finally returned home in south England. I have just topped the tank and calculated that the car has returned 42.4 MPG.
Very pleased. - recommended
