Customer: Tim. Birmingham. MB E320

My E320 Diesel showed a noticeable improvement in performance from the …bhp increase on the remap and has become more driveable as well as quicker and more economical in the process (by about 5mpg on a long journey). Diamond Performance really seem to know what they are doing – so much so that a friend has had his E320 Diesel re-mapped as has another with a VW Touareg.
